Motorola Motonav TN20 - 3.5 in. Car GPS Receiver

This is one of the best GPS units for the money. I purchased mine at Radio Shack for approx. 140.00. It already had the latest road information programmed into it. I even use it around town to find some of my daughter's friends houses when she goes for a sleep over. Using it on vacation proved it invaluable. Most impressive was the way it changed the posted speed limit right as you passed the sign. It has a huge selection of voice prompts. the most helpful one to me was "You are exceeding the speed limit" lol. It really did save me from getting pulled over. You can also silence any or all of the prompts. It can display the majority of businesses like hospitals, stores, gas stations and even pharmacies which is helpful if you forget to fill you meds as I did. The unit will announce an exit one mile from it, then half a mile, then in two tenths of a mile and the actual exit. It also displays how the exit will be. Sweeping right or left. Merging type or stop sign. Very helpful. At the bottom it will display distance to destination, how long it will take. One draw back is it doesn't recognize oneway streets and that is the only draw back. It has either a suction cup for the dash or a mounting plate that has a really sticky back.
