Hi Jochen,
I have been doing mucho research on the net lately and it seems that u are the man who may be able to help me - I hope.
I live in the UAE and have recently purchased an E39 (1999 model) which is a Japanese import. The vehicle has Japanese Navigation installed but I have no idea what Mk it is. The head unit has the 4:3 display and the computer (which is mounted under the rear parcel shelf rather than in the left hand guard well) is labeled "DVD Navigation".
A Japanese Nav DVD was in the player when I got the car but I think the player is stuffed cos it just shows "DISC" followed by a bunch of Japanese characters when I select the nav. If I reload the disc I occasionally get the icons along the bottom of the screen before the Disc message comes up, so I think everything else is working Ok - the TV works fine.
Also the radio shows the Japanese frequencies - I have fitted a fx shifter but it doesn't seem to work very well.
My question - which is obvious - how can I get it all to work here in the UAE. I have the latest 2007 nav disk for the UAE. Can I just swap the head unit and the DVD reader for one from a UAE spec vehicle - will changing the head unit also change the radio frequency display (i was planning on finding a widescreen from a later model) or is there something else (radio module) that needs to be changed also.
Is the '99 E39 wiring compatible with the later Nav systems?
Any info/assistance/help would be greatly appreciated.
I gather from some of the posts I have read that u can supply a kit - would that be of any use to me?
Thanks in advance for any help
Regards
Paul Ashford
