What are the necessary features in a GPS device?
I am buying a GPS for my car and this is my first time doing that. So I am totally clueless what to look for. Wondering what additional features ,beside the main functionality, are out there in different brands so that I could select a device based on my needs. I am looking for features like line assistance, recency of the map database, or anything else that you may think matter when buying a GPS device,
Thanks everyone
