Hi People, About to go pick up my new 307 St.car at the end of this week, i would like some recommendations as far as navigations systems go. 1. I have been looking into the TomTom Go 500/700, but is it true that an external antenna is an absolute "must"? I heard that the Tomtom Go "One" can work without external through the coated windscreen. Any word on that? 2. I have heard that the existing radio antenna can actually work as an external GPS antenna. I believe i saw someone on the internet citing his instruction manual. Anyone know if this is true? Anyone with experience? 3. Mounting. I would just die (or just about) to see some pictures of Tomtom Go's (or other devices) mounted in a 307. I want to minimize cable clutter, so any suggestions/pictures/advice would be much appreciated. I am looking into the Tomtom Permanent Docking kit, also. Anyways. Have been driving a Citroën for about four years now, having had nothing but trouble with it, so I'm looking forward to getting back to a Pug. :-) Thanks J. Jespersen Denmark
