Cool E46 BM53 MK4 Navigation Integrated Bluetooth Voice Command for Less than $100 DIY

I am making this E46 BM53 MK4 Navigation Integrated Bluetooth Voice Command for Less than $100 DIY thread separate from the original thread for those of us with the OEM 16:9 Monitor Navigation incorporating the MK4 and BM53 Radio Receiver in the trunk.

NOTE: This thread will cater to BOTH those with the original 16:9 BM53 MK4 factory navigation that came with the 2002 to 2005 e46 BMW 3 series cars from the factory and those who retrofitted the OEM MK4 BM53 16:9 CD/Tape Monitor Navigation using the BMW E46 Navigation Retrofit Harness.

For those like me with the Retrofit Navigation Harness used to retrofit a full Navigation kit to your e46 car for your installation you will need the

1. Parrot ck3000 Bluetooth kit or Eclipse BT-E600 Bluetooth kit (off eBay whichever you find to be cheaper. They both are identical). Price Ranging from $20 to $100+

2. Connects 2 CTPPAR007 (see original thread for details on where to get this). Average price is around $50 to $80.

3. Follow the original thread for installing and prepping the ck3000 and ctppar007 here:

This DIY is for adding Bluetooth with Voice Command features to your 1998 to 2006 BMW E46 Sedan, Coupes and Convertibles. This DIY focuses on integrating an aftermarket bluetooth and voice command into the BMW Business CD53 Radio (all year Blaupunkt or Alpine models) so that you control your mobile phone's incoming and outgoing calls only using the steering wheel buttons and your voice.

The DIY difficulty of this project is very easy and takes the average Joe about 30-40 minutes. The only tools required are clean fingers, a star point screw driver and flat clean dull butter knife for prying the dash trim off. There is no splicing wires, no removing seats or console armrest, no adding antennas on your roof or digging around your trunk for cables. This DIY ONLY requires removal of the Radio, Center Vent and Glove Box (total of 10 screws) and everything else is plug and play. Some DIYs state that removal of the A P!llar is necessary for running the mic to the headliner but I will show you that it is NOT necessary to remove the A P!llar.

The cost of this DIY can vary. You will need to purchase the Connects2 CTPPAR007 steering wheel integration kit from the UK vendor
( http://www.lowcostcaraudio.co.uk/lcc...er/pid/7642231 ) and their price is set at 49.99 (about $80.00 USD). And next you will need to order the Parrot CK3000 Bluetooth kit (it is also called the Parrot ck3000 evolution) which can cost from $9.00 and up on eBay. You do not need to buy anything else nor can you substitute other Parrot Bluetooth kits or aftermarket Steering Wheel/Radio Adapter harnesses. It will not work here. Also do not get tempted to save money on the CTPPAR007 and buy another similar Steering Wheel Control Adapter harness-and they are lots out there that claim to work with various bluetooth kits. It will not work here. This DIY will ONLY WORK with the CTPPAR007 and the Parrot ck3000 together!

When said and done this DIY will upgrade your BMW with much of what the OEM Bluetooth does including instant and automatic pairing and unpairing when you enter or exit the car, one button touch voice command, one button touch redial and full radio and steering wheel integration. The only thing you will not get is full Caller ID read out on your radio display-instead it will display PHONE or WAIT. This is something I can do without as I may have people sitting in my car and I do not want them to see who is calling me (see under girlfriend).

PART ONE: Looking at what we got

Here I got everything I needed off eBay. You need the CTPPAR007 kit which you can also find on eBay or eBay.co.uk. The vendor states that the CTPPAR007 is for the 1998 to 2001 E46 and the CTPPAR008 is for the 2002 to 2005 E46. This is wrong the CTPPAR007 has the 17 pin style connecter that all year BMW E46 cars and all year BMW Business CD53 Radios come with.
The CTPPAR008 is the flat style 40 pin connector that is found on the 2006+ E90 BMWs. So that will not work on the E46.

When you open the Parrot ck3000 kit you will see the obvious main bits (the blue box, the mic and the controller) and you will also see a bag filled with a few wire harnesses and a black rectangular module for connecting to the radio and allowing for the mute function. You do not need this since the CTPPAR007 will replace this portion of the ck3000 kit. Also you MUST HAVE the ck3000 Controller connected to the main blue box in order for the CTPPAR007 to make the steering wheel buttons work with the kit. You do not need the controller on your dash when using the Bluetooth as it only needs to be connected so you can tuck it behind the glovebox with the other modules.

4. And as you are retrofitting your Navigation monitor this picture BELOW should make sense to you. Even if you are installing the Bluetooth kit after the fact the picture should still make sense as you are removing what you previously installed and connected behind the Nav monitor in your dash:

All your connections will be in the front of the car with the ck3000 Bluetooth ECU and Connects2 ECU stashed behind the glove box.

The Connects2 CTPPAR007 17 pin bridge connectors will then be used to bridge the retrofit harness' 17 pin connector (whose other end goes to the BM53's 40 flat pin connector in the trunk) TO the original 17 pin connector that goes into the car.

5. Those who have Navigation that came originally on the car from the factory your journey will be slightly different. You will need to purchase the Parrot ck3000 or Eclipse BT-E600 kit and instead of the connects2 ctppar007 you will NEED the CTPPAR008 that comes with the flat pin connector for the BM53.

BM53 40 flap pin connection:

CTPPAR008 40 flat pin bridge connector connects2 kit:

All your connections will be in the trunk where your BM53 is and NOT the Glove Box/Dash area.

6. Once this connection is made you will have a fully operational integrated in-car Bluetooth and Telephone Voice Commands (depending on your cell phone and cell phone service) operating off the Steering Wheel and Navigation Monitor buttons.

Here is a video sample - towards the end of the video I demo the Bluetooth/Voice Command Features. My phone is a T-Mobile Blackberry 8900 Javelin Curve with the latest 10/2010 Blackberry OS upgrade.

Please Help. In my 04 M I dont have Navi but I have the S.O.S. rear view mirror. I tried to call BMW assist with it and it works. I tried to look up the bluetooth key under the TCU but the sticker didnt have the code for it. What can I do to get my BT working.

I'm not sure how the OEM Bluetooth works. All I know it is VERY expensive and uses more parts and bits than toys on the floors at a day nursery.

I'm surprised you got the SOS working that means your Bluetooth is active (if you in fact dialed thru your phone.) As for the TCU security code sticker that is something new to me. I assume it is the pairing code you are referencing. The universal default pairing code is a 4 digit number and is usually 1-2-3-4 or 0-0-0-0

More information on Bluetooth and Bluetooth activation here:

After a long search found out that i did not need to buy any thing to put bluetooth to work on my 05 325i sedan. I contact Brian at Circle Bmw and he gave all the instruction how to do this. Here are the information

BMW Assist with Integrated Bluetooth (If your car is in this range and has the pre-wired phone tap on the rear trunk door inside you probably have all the parts installed like i have)

E46(3 SERIES) from 9/04 production (325i/iA from10/04 production) with Premium Package (ZPP) or BMW Assist (SA 639) comes already with every thing and you just have to do is the Pairing Procedure

Paring Procedure for I/K-BUS Vehicles ( E.G, E46, E53, E83, E85 )
1) The customer handset must be verified for compatibly, visit WWW.bmwusa.com/bluetooth for a list of handset that has passed BMW testing for compatibly. ( My is a SAMSUNG and work perfect )

2) Turn the key off and then to KLR or KL15. ( I just turned the key from off to the next position)

3) The vehicle is ready for pairing for the first 2 minutes of key on.

4) If the R/T( ON THE STEERING WHEEL) button on the MFL is pressed, "Activate Phone" appears on the MID or Board Monitor.

5) Druing the pairing process, depending on the equipment, the indicator lights on the MID or Board Monitor display flash.

6) Your mobile phone should now be set to search for BT devices. See the Owner Manual for your handset.

7) A request to enter a password, PIN, or code appears on the handset display, depending on your model. Enter the Bluetooth Passkey (SUPPLIED WITH THE VEHICLE LITERATURE. I had to take out the cover on the driver side in the trunk to remove the the Bluetooth Module and fine the passkey number that are 4 number only)using the numerical key on the handset, and confirm the input. Look for a confirmation message on the handset.

8) To conclude the pairing process, turn the key off.

9) Wait approximately 30 seconds before turning the key back on. The phone will now be connected when the key is turned on. It may take several minutes to initially load the phonebook stored in the handset, depending on the number of entries.
