Well I installed it this morning. No real issues with the physical install & wasn't doing a camera. It fits fairly well, certainly enough for me not to be concerned. Bluetooth works fine with my Nokia 6300; DVD's play perfectly; Audio CD's & MP3's play perfectly; Radio is very clear & managed to get the steering wheel buttons working to some degree although more tweaking required. Manual instructions are not that clear to me; Not interested in TV or IPod connections so left them alone. NOW - the GPS does work as I took imposter's suggestions re the SD card first. Imposter - do you know if this unit speaks the street names? There is a section to set up voices which I have done but I don't get any when the GPS is in operation. The manual says to "See User's Guide of GPS Satellite Navigator for more operation details" - that would be great if there was one, I can't find it not even on the supplied CD? The 2nd thing is when the GPS is on, is it possible to listen to the radio? I can't work out how to do this if in fact it is possible.
