I use the Kenwood system. By far the most expensive but it works and as a business expense for my Van was well worth it. I never worry about getting lost.
When I travel by air and have to rent a car I use my XV6700 cell phone with TomTom software and a BT sat receiver. It works OK but when you get spoiled by the best it is hard to get back to these smaller basic systems. The goofy thing about the TomTom is it zooms the map by your speed, which may seem ok but in practice it often is a problem.
