Well I got the map problem semi sorted out. Not perfect but I can live with it. New glitch now. I'm getting the message "this accessory not supported" now. I reset the GPS back to factory settings. The traffic receiver I used is a GTM 60. I also tried a GTM 39. Still got the same message. There are not traffic broadcasts here in the local area so I don't know if that's the problem or not. My other Garmins don't give the message when using the same receiver cables. Jim
