Can you use Tom Tom maps on Audi?
There is a great deal of discussion regarding Tom Tom and Garmin comparisons and the conclusion seems to be that one should buy the one that suits them most. Tom Tom offers clear display, live traffic information but one pays for the updated maps. Garmin has smaller models but the maps are updated continually and included in the price.
I have Streets & Trips 2008, and it works very well with its own maps. But it is not possible to add new maps from other systems. It looks like it will never have interface with other systems, because it was on purpose. You need to do an upgrade and pay for the service if you want to get new updated maps. Greetings, Mono Castro
