Hi,
I’m looking for a sat nav to work with my Interphone 4 & iPhone 4S.
The 340 looks to be the latest technology but the 660 seems to have the most features.
Looking on-line I can get the 340 for £230 including lifetime European maps or £285 for the 660 with lifetime European maps.
From the reviews that I have read the 340 may not be as robust as the 660.
Opinions please.
