Looking for a new sat nav now that the Vec is going and the Mada doesn't have it built in.

Essentials are external antenna socket and TMC reciever as I wont be mounting it on the windscreen.

Heres the Harmon - http://www.guideandplay.eu/eng/main.html

Both the 910 and 810 come with 2.4Ghz wireless controllers too which is nice.

Any opinions or other makes that can be recommended?
