Yeah, just spent a boatload today putting in the orders for all the audio pieces I need. Since my X5 came with 16:9 nav + DSP, it's not quite plug and play for me. Had to purchase a 5 channel amp, RCA cables, and crossovers to set it up properly. As soon as everything comes in, I'll be spending a weekend taking the OE nav and DSP units out and installing everything in. Got the whole install planned out based on all the research I've been doing, but will probably take me a good day (maybe 2) to get everything installed. Could probably do a write up, but then there's already so many info on the different X5 forums already.

Only thing I'm still iffy about is the install of the rear view camera. Will probably just run the composite video wire from the Dynavin to the back first and take my time on the camera installation on the rear hatch.

Will definitely post some pictures once I have things installed.

I was debating between the Windows CE and the Android version as well. Decided to just spend the extra $50 to get the Android once I found out that you can just get offline nav software that would be the same as the Windows CE. And the Android version will be more versatile in the long run. That was my thinking.
