I had heard nightmarish stories of needing to run harnesses from the trunk to the dash and all kinds of craziness. WellI did end up finding the Dynavin, which looks exactly like the OEM Nav in the E46's, from a vendor on eBay for $599 obo with 1yr warranty. I'd like to make clear that, at least the unit I got, you don't need to buy anything else. IT WAS ENTIRELY PLUG AND PLAY. It took about three hours total time, and the most difficult part for me was running the GPS antenna in the roof without interfering with the sunroof mechanisms. The first thing you'll want to do is obviously disconnect the negative battery terminal, just in case of any "oopsies" that may occour along the way, and so you don't get a face full of airbag when you're running the GPS wire. Next, you pull the trim located below the passenger side airbag as well as the trim piece above the radio off, simply by prying it up gently with a plastic putty knife or something to that effect. Remove the two screws that secure the A/C vent cover and the radio unit in place. Pry out the radio and disconnect the 17 pin connector as well as the antenna wire, and remove the radio completely. Next youll want to push the climate control panel out from the back side. Just apply controlled pressure and it'll pop right out. Remove the four electrical connections plugged into it, and place it somewhere out of your immediate work area. Next you'll have to push out the storage compartment, again from the backside to expose two of the four screws that hold that bracket/housing in place. From this point I prefer to put the car's shifter knob into "D" (if automatic trans obviously) to accomidate the space that'll be helpful when removing the ashtray/ storage compartment bracket. Then you remove the shifter knob by giving a good firm pull upward, and remove the boot surrounding it. This will give you access to the remaining two screws necesscary to remove completely the ashtray bracket. Next I ran the GPS wire into the roof by removing the maplight fixture, the passenger side sun-visor light, the sun-visor itself and the passenger side a pillar. Hopefully that paints a pretty decent picture of where I ran my wire. Next thin was to remove the smaller (10 pin) connector from the stereo harness itself by removing the blue clip and just push the wire aside. Now you connect the Dynavin connector to your factory connector and secure it by pressing down firmly on the top. (important note: coming out of the Dynavin's harness is a few cables that run to a box labeled "SY8" make sure you plug the matching connection into the other end of that box and into the black cable labeled "IR") This connection will ensure you do not lose your steering wheel control function. Also, I went ahead and took the parking brake wire coming from the back of the Dynavin and spliced it into the Black ground wire from the unit itself. (This may be ill advised and it is illegal to watch DVD's while driving, but whatever, do what you can afford I guess) There is also a different style antenna wire than the one the HK business uses, but the Dynavin comes with the adaptor, just make sure you hook it up if you want am/fm. From there i just plastic wrapped all my unused RCA's together and kind of shoved em in next to the airbag. Fitting all the wires and new connections in there without jamming the crap out of em was kind of a pain, but hey, it is what it is. Next, put in my climate control/ ashtray bracket that I got for likr 68$ from pelican parts, and plugged everything pack in and put it all back together. I'm sure there's a few small details I left out, but it really was a pretty simple install. Downside to it all is that the Dynavin manual is written in HORRIBLY translated English, and doesn't go into any great ammount of detail about the wiring, or setup. Upside; IT ROCKS and it's only $700 bucks. You'll have to go through and establish GPS antenna signal , and bluetooth,for handsfree and all that, but it's a pretty cool unit. Well worth the money, so for anybody out there looking to retrofit your E46 with Nav, and you hear all these stories about $2000 bucks. Blow it off man cuz it's BS. You don't need any 300$ harness from bimmernav or any other vendor. The only guy I would reccommend is jeff and he's on here. He is probably the most knowledgable about the Dynavins and E46's audio systems in general. Hope this can help someone out there or al least allow someone to breathe a sigh of relief when you find out that the OEM NAV "look" doesn't have a $2000 price tag. Thanks-
