Fairly easy to work it out, as you can see there was a space foreseen for the HSE version, which includes a factory-fit display. Only had to make sure a 7" would fit, and it did.
Kept the BT carkit from Nokia, kept my Garmin GPS and use it's dataport for nRoute and Centrafuse.
Integrated a remote controller for our garage doors as it works on 12V as well.

I set off with a very old mb (P3, 666MhZ, 256Mb Ram, 64Mb AGP), but it still works pretty well.
