Query: Great GPS

I bought the C550 for my 72 year old father. Even without a lot of technological experience he can operate it just fine. Very easy. All the options neeeded to get him where he needs to go, without having paid for a lot of extra stuff. With the voice and crisp, clear screen it is very easy to see and follow. My husband and I used the unit on a out of state trip and we loved it!! Highly recommend.
