I put together a satnav retrofit kit for a schmuck a couple of weeks ago. Spoke to him on the phone, had his address, and knew of his business website (was part owner of a tile store) so I decided not to ask for a deposit. The schmuck has now disappeared completely - he even duped his business partner! My own fault for being nice, I guess.

Anyway, I now have all the bits laying around: head unit, Mk III nav, BM 54 (latest BMW version - has Aux-in and shows MP3 ID tags), plug n play loom (not avail from LR!)...
