Hello all!
New to this site, only found it a couple of days ago, bloody brilliant though! Picked up my 172 about a month ago, had sat nav fitted and it is an excellent toy, and its actually useful sometimes as well! Roamer if you dont mind me asking were did you get your different cd from? Cant get that TMC thing work at the moment.
Sorry I havent got any pics, but display is clear and the map is very accurate. If you can afford the option do it, and push the dealer to give you at least 10% of the option price, its their staff discount or something so just push until you get it.
