| Yes it can be done, but its not easy.
You will need a brand new, never been coded before, centre instrument pack and NAV Screen, very expensive from a stealer!
After fitting you would then need the new pack coding to the car by the dealer.
The you would need a DVD to RGsB converter to feed the video to the screen. Not impossible but again expensive for plug & play unit.
Would be easir to fit a composite 6.5" screen into the centre pack instead of using the MINI Sat Nav screen.
How much of a challenge do you want? |
