Hi everyone! I have not updated my Garmin Mobile XT (WM 6.1) since 2011. I've tried the unlocked maps posted on this site for every year since 2012 and I have not been able to get it to work. Do these newer maps work with Mobile XT 20w? Not sure if I'm missing any steps, but I think all I need to do is enter my device id into JetMouse to get the code for gmapsupp.unl. Do I need other things to get this to work?
