Retro fit navigation on a 2007 X3?

[mhainen]

I use an older Garmin V and love it. I use it on my BMW touring bike, and all my cars. It is small, but easy to read the turn-by-turn instructions. It has nice back lighting when plugged into the vehicle power. I can even carry it as a hand held unit. Granted it is not color nor does it talk to you, but I only use it when I am looking for a specific address or restaurant in an area I am not familiar with. The other downfall is space to load a significant amount of detailed mapping. I just plan ahead and download area I am traveling too. I still like to use a map (I guess I am old fashion)You purchase these things for about $300-$400 (if they still make this model). 99% of time I never use it.
