| You can use any of the NON widescreen Garmin units. I have the 255, it can bought for less than £100 if you shop around. BMW want £145 for the same one.
The mount can be self fitted but apparantly its a pain, my Dooper is going in weds for one fitting, they are charging me £91.50 fitted.
I dont need to make my car go faster, I just need to learn to drive it faster. |
