Hi,

Thanks for your reply.

I already have a 16:9 display from bimmernav.com and the bits to move the air con down.

If you look at the sticker on the nav computer, you will see that it says HW 21 SW 40, but the display reads 2-2/40 or 2-2/90 since I did an upgrade.

Dose this tell anything to anyone?

So if I get a MK4 dvd computer it will be plug and play?
