I am going to be headed to Paris for a trip in the near future and would like to get a handheld GPS that gives good maps of city streets and good directions from one address to the next if possible. Am I going to have to get a GPS like you would put in your car, or are the other handheld type devices capable of this? Is there a better option (other than a paper map or a phone app) than the GPS? Sorry if these are dumb questions, I've never used a GPS that wasn't in a car. Thanks very much for any info!
