I love my Q7, but the Acura Navigation works much better than Audi Nav

What are the differences?

More acurate information (in the last two weeks, my Q7 nav got me to wrong locations), you can also use the navigation as yellow pages, you can look business addresses by telephone number, you get more business addresses (with audi you only get malls, instead of store name, supermarket,...). I think this is a navtech issue.

I was fascinated by a friends allroad during a visit over the Holidays and was allowed to read the manuals and play with his nav system (several hours over a few days). It seemed a slick system. My wife and I were planning to buy a new car and it won us over to Audi.
That said, we test drove a number of vehicles, including several Acuras and were even allowed to try one overnight.
RAD2 is correct. The Acura nav system had more useful information and a clearly superior interface. Noticibly fewer steps to get to information and it seldom required looking away from the road. We travel all around the Bay Area (SF) and having clear, real-time traffic and Zagats restaurant information so readily accessible would make exploring unfamiliar neighborhoods a real joy again.

Along with reliability, we viewed the bluetooth nav system as Acura's best selling point, but went with an Audi (tech package) anyway. Audi's quality design and materials are unbeatable.
