My Ride: 2002 BMW 325xiT
iPhone 4 "integration" hack in a 2002 325xiT with factory iPod dock

Here's some real-world data for anyone trying to make use of an early model factory 30-pin iPod dock in their e46...

I recently bought an '02 325xi touring/wagon that came with the Business radio/single CD stereo head unit, Harman Kardon surround sound speaker system, and the factory iPod dock installed in the glove box.

When I connected my iPhone 4 to the dock, I could get music to play through the stereo just fine, showing up on the head unit as coming from the nonexistent CD changer (by presumably hijacking that input on the back of the stereo).

My phone didn't charge however, since Apple apparently changed from firewire to USB charging in about 2007. So I had to buy one of these to adapt the iPod cable to allow charging.

Still... although the glove box iPod dock concept was a pretty cool and stealth solution back in the days before do-everything smart phones, having my iPhone 4 buried in there wasn't exactly what I had in mind for car integration. I wanted it out and mounted on the dash where I could use it as a navi and to take phone calls too.

So... I bought a dash mount and swiveling holder from ProClip to mount the Phone, and both look and function great.

But how to get audio to the stereo?

After reading this thread over on another M3 forum, it looked like I had a shot to get wireless bluetooth streaming working from the dash-mounted phone to a bluetooth dongle attached to the iPod connector in the glove box (the perfect lazy man's solution).

Sadly, I'm here to report that, although this solution seemed to work great for others with newer cars and/or non-factory iPod docks, the devices I tried (here and here) didn't work with my factory unit.

The dongles seemed to draw power just fine, they would light up to indicate that it was time to pair, the phone would recognize them and pair, but the sound source never came up when toggling the "Mode" button on the stereo.

Finally, I just opted for a hard-wired hack (see pictures below). I removed the glove box and enlarged the cable access hole slightly with a box cutter so I could free the 30-pin connector from the glove box interior. The connector and charging adapter can now reach all the way out to the dash mounted phone, with only a small white tail emerging from the corner of the closed glove box. I tuck the cable and adapters back into the glove box when not in use.

Having the cable pull out through the ash tray would be better, but I didn't see any easy way to route this. Anybody know a better solution?
