I have a Garmin unit and in 2009 bought a GPS map for it from, I think, PTY GPS. I want to get the update but am getting conflicting info about who to contact and how to get it. There is a dispute of some kind apparently and I don't know what's right and wrong. Steve is the guy who installed it for me years ago at his house near the city, now another guy has sent me an email saying he is a "thief" .... what is the opinion on this forum?' Where should I go to get a good Panama GPS map??
