I am looking into getting a GPS, don't know anything about them. My wife won't go to the Sound or the San Juans without one.

Do you think a GPS is necessary for those applications or a waste of money?

What brands are recommended?

Dash mount or handheld with mount?

Sorry for all the questions, any help would be appreciated including input on any other questions you think should be asked about a GPS.

Thanks.

Sincerely, Doubletake
