I wanted one in the car as they say not to leave the clip in the car and not to leave any marks on the windscreen. Also, I think with the traffic avoidance on the Tom Tom it uses your mobile to call and check which is more ££ at least with the
TMC it does not cost any more. Not to mention the nice display on the EX showing the track and folder names on mp3 discs & CD-TEXT discs.
