USA-Spec PA12-BMW Integrated iPod Full Video Review and Pictorial Installation Guide
My Review of this wonderful device on my 2001 BMW 330i with an upgraded 02/2006 Alpine CD53 Head Unit.
EDIT: 02/23/2010 (added and tested Auxiliary Input cable)
EDIT: 03/01/2010 (full range of the usa spec functions reviewed and discussed)
This USA-Spec is installed in a E46 that has the factory gen 1 BMW Sirius Receiver and an integrated Bluetooth system and everything is working perfectly in harmony.
Key Points Of Review:
-Kit Quality; The USA-Spec get high marks for this. Everything is either aluminum metal for the body or high grade tough rubber for the cables.
-Playlist Features; The USA-Spec will fall short in this department for two types of people. The first are those folks who tend to carry tons of Playlists in their iPods and second are those that don't use Playlists at all and organize song playback by artist or album.
The USA-Spec reads from BMW1 thru BMW5 Playlist that the user creates beforehand or the USA-Spec will read the first 5 playlist stored on the iPod. It is a Playlist dependent device. But I like this feature because it is clean, 100% bug free, functional, easy to use and quick.
-Connecting the iPod and iPod Storage ideas in a BMW E46: ipod connection is quick and I love that the Spec starts playback from where you left off with the iPod. So literally you can leave your car for months with your iPod then comeback to your car and the USA-Spec will return to playing the song you last heard.
-Sound quality; Was the biggest treat of this kit. It is superb on my stock HK system! The USA-Spec is very generous with the Bass so having Donkey Kong bass in the trunk feeding off your iPod is still an option with the Spec.
-Ease of use; Very easy. I had the DICE 1st gen in my car for a day or two and I didn't like how complex the features were. I use my iPod for primarily 2 Playlists: New Music and Podcasts with other minor Playlists dedicated to my favorites in various genres from R&B and Jazz to Rock, Electronica, HipHop, etc...
The DICE when it worked required too much setting up for me inside the car (in organizing Artists/Albums/etc....).
The USA-Spec, once you have your Playlists pre-managed and set up on your computer, your iPod is plug and play.
-Any bugs or issues; After a week of heavy use they were none with the kit. During the video review's many outtakes I realized that the iPod itself did not like being constantly plugged in and out from the car (about 20 times in the space of 40 minutes) but it didn't freeze up, mess with the car or required any major battery or dealership reset. The iPod only turned itself off to the apple screen and turned back on.
-Cost; I got my kit for only $90-something bucks new off eBay an dthe prices of these are around the low $100s. For what you get I think that is a great bargain. Plus if you don't like it, sell it back on eBay because the unit has strong resale value because it is a good kit.
I totally recommend this kit for anyone who, like me, wants to get in their car, plug in iPod, press play and drive. I don't like speck docks or cables and cradles in my way, nor do I like managing copious amounts of playlists and ways of playing my music on the fly. With the USA-Spec you do it all at the computer so you don't really have to do it in the car. Plus with the RCA AUX-in adding HD radio, Aftermarket Sirius or another source of music in the car is easy to do.
Here is a quick run down of the other competitors:
For iPod Data Connection you will need either the DICE Silverline kit or the USA-SPEC PA-12. Both these kits are the top two leading kits in terms of performance (USA-Spec) and popularity (DICE) and both cost just under $150 (cheaper on eBay). The Dealership also sells their own spartan iPod retrofit kits priced at around $185 to $200 and performs more similarly to USA-Spec than the DICE.
Now onto the basic installation for the USA-Spec. This is the same for the DICE unit that goes in the trunk:
PART ONE: Prep your car for installation.
I had previously installed a BMW Sirius Receiver in my car so I will show that part here since it is also important to show how I slaved the USA-Spec unit off the Sirius Unit which in turns carries all the information to the Data Link #1 port on the back of the CD53 Head Unit.
For folks that do not have a BMW Sirius Receiver, and do not have a BMW Factory CD Changer in the trunk you can skip thru this part and connect your DICE or USA-SPEC or other Data Unit to the pre-wired CD Changer cables that are in your in the trunk as shown above ( the felt wrapped cables that I'm seen unwrapping to connect to my Sirius Receiver).
If your BMW E46 did not come with any pre-wiring for the CD Changer you will need to buy the Data Link Cable BMW Part# 61128374683 (see image below) which costs around $40 to $60 at the dealership and install it yourself from the Data Link Port #1 to your iPod Data Unit. Those doing it this way will have the advantage of leaving everything inside the cabin of the car since you can opt to keep everything behind the dash area.
01 CONNECTION CABLE CD-CHANGER 4150MM 1 61128374683 $25.50
Those who are using a Sirius Receiver or a CD Changer already in the trunk will have to get the Slave Data Connector OEM Part #84110150526 and use it to connect the iPod Data Unit directly to the Sirius/CD Changer which will in turn connect the iPod Data Unit to the car. So when MODE is selected after SIRIUS you will access your iPod as if it is a CD Changer. This first part is for you guys:
Picture of Slave Cable below borrowed from SNA77.
Now onto the pictorial installation guide:
I previously planned on using Data Port #2 on back of the business CD53 Radio to support the iPod Data in the identical way that Data Port #1 supports the CD Changer/Sirius but I was wrong.
Port #2 will NOT WORK on its own for Data Input support. You can add your iPod Data or 2nd Data Source (IE. CD Changer slaved to Sirius) with a Slave Data Extension Cable branching off the Sirius Receiver/CD Changer. In this case the BMW system gives hierarchy to Sirius as master always and the Data iPod or CD Changer Slaved off of it. If Sirius isn't present but a CD Changer is then the CD Changer must be the Master to Data iPod.
That said you most likely CANNOT have ALL THREE (iPod/Sirius/CD Changer) in your car at once using just the normal Data Link Pre Wiring Cable and Slave Data Cable.
INTERESTING SIDE NOTE: There is a DIY-mentioning from last year where a member at e46fanatics BMWAudio32 from Columbia, SC discovered, while trying to remedy the DICE/Sirius ghost feedback/alternator background noise, that you can actually splice the trunk bound ends of the main Data Link Pre-wire Cable and create two sets or multiple sets of Data Link ends off the main cable leaving the Data Link Port #1 on the back of the CD53 head unit. Then with placement of a homemade toggle switch along the junction where the separate branches meet BMWAudio32 was able to choose from multiple Data Sources (whether it be iPod, Sirius or CD Changer) in his car by flipping the homemade switch between the branches when the SIRIUS/CD CHANGER MODE was selected. This method successfully "fooled" the head unit into thinking there was one only data source when they were actually multiple. The only downside is the DIY time and skill required as well as the non-OEM look of the homemade switch placed in the cabin. Other than that it allowed for multiple Data sources that did not interfere with each other at all and eventually created the best solution for dealing with DICE/Sirius/CD Changer interference noise and issues when slaving various Data Sources.

That brings me to my choice in the USA-Spec which was very well reviewed and introduced to the e46 community by Steve325i from e46fanatics. As a less popular unit than the DICE, The USA-Spec is cheaper and has all the features of the DICE including an RCA Aux In Port. The only reported disadvantage of the Spec to the DICE is you are only allowed access to up to 5 User-Set Playlists (Or the option to just Play ALL SONGS on iPod) while the iPod is in fully integrated mode.
The DICE allows for access to more or all the Playlists on your iPod and text display is given for the Playlist. The USA-Spec was fine for me since with Sirius, AM/FM, 100s of songs on my MP3 Data CDs, and AUX input in my car I already have unlimited access to hours upon hours of fresh music. Accessing only 5 Playlists off my iPod would not kill me or be a deal breaker. Albeit the 5 User-set Playlist can have unlimited amount of music in each playlist with respect to the size of your iPod.
So you CANNOT argue that the Spec gives you access to "less" music than the DICE would. It just gives you access to less playlists than the DICE would.
Said and done my install, after a few Darwinian/Homer Simpson moments, ended beautifully. The USA-Spec, when done properly, installs and works smoothly without any of the reported issues you get from the DICE.
VERY IMPORTANT NOTE: You MUST fully unplug your CD53 Radio and unplug your car's battery before connecting the iPod Data Module to the car. I forgot to do this on my first attempt and my Odometer/OBC and Radio Display fizzled and pop and the text display went all Klingon on me.
I quickly disconnected everything immediately and was lucky enough to not damage anything.
After the second install attempt went smoothly I opted to run the Spec's long Data Cable into the cabin from the trunk to the USA-Spec Module in the glove box area. The Spec also comes with a lengthy iPod Cable, though not as durable as the burly Data Cable, which I snaked under the centre console/arm rest area.
Unlike others that did this before me I did not drill holes or cut and splice cables to squeeze my iPod into the E46 Armrest's tight lid pocket. Nor did I want my iPod out in the open and in the way.
I wanted to get in the car plug the iPod in and lock it away in such a place that it would be fairly immune to theft (IE. Not in the glove box or ashtray), not taking up visual space in the dash/console area yet still be easy and quick to access.
The best place I found was under my Euro Tray. There the iPod Touch could fit, be out of the way and accessible in seconds by pulling up the Euro Tray (or cup holders if that is what you have).
NOTE: the coin holder that rotates/flips up (it usually comes standard behind the cup holder on the USA E46 cars) will not give enough space for a large size iPod (like a Touch). You will need to replace it with some version a Euro Tray or the flat storage tray that sits behind the cup holders/or short Euro Tray and replaces the coin holder. In the picture below the Red X denotes what NOT to get. The other segments are fine for storing your iPod under. (Also there is a very rare segment that is a small flat open holder tray) not shown here that directly replaces the coin holder in the rear space behind the either the USA cup holder or short euro tray that will also work.
Man, that was a very good write up. Nice job!:thumbsup:
Still, looks like a good kit though.
man your write ups are the best
Very good detailed write-up! Thanks
Nice writeup. Does your car have the HK system? I'm not sure which kit to get, PA12-BMW or the one with DSP.
All the model year BMW 3 Series E46 DO NOT come with DSP.
Only the 5 and 7 series have DSP as an option on their respective radios.
DO NOT GET DSP in this USA-Spec kit if your car is a 3 series BMW!
Delmarco, you have outdone yourself again.
Truly, thumbs-up :)
Just one quick question ... what was the ambient temperature while you were performing this DIY???
So is there anyway to connect this directly to the OEM HU without going through the whole trunk setup? I was expecting it to plug into the back of the OEM Alpine CD53 HU and run the cable down to the center console and through the armrest area for my iPhone... Is that doable?
Got my kit today and plan to install it this weekend.
Incredible write-up, what a good job, man! Thanks!
Now I get your preferences about what to play, but I assume you are not generally limited to the playlists - you have a mode where you can just operate the iPod on the iPod and thus access music the way you always do on your iPod - right??
For some of us, this is the only real way to operate your iPod - I have more then 18,000 songs on mine and there is no way a small text display will work for me while driving to select a song.
I had mild frost nip for the following two days from taking my gloves off and touching the metal bits in the car. :eek:
You make me want to sell my dice unit and pick this up :(
will this work on 1999-2000 radios?
