Hello to All I have recently purchased a 665 for a steal of a price. I am a music buff so the XM lured me in. It does not have any maps for Mexico loaded in it and was wondering which map to buy from Garmin? Website https://support.garmin.com/search/shopResults.faces?site=Shop&q=mexico&Go= My interest would be the Copper Canyon southern Chihuahua and Baja. Being a kind of a newbie with this type of GPS use (beyond inner city use), I need some advice. Do I buy the Mexico maps or the South American maps w/Mexico included? Thanks for any advice Rode
