I suspect your problem may be to do with the fact that you have an 'unofficial' unlocked map on your unit. Is it named as 'gmapprom.img' in hidden .system folder? That's where mapupdater is trying to install the LM update, and it's probably not liking what it's reading there. Do as Strephon Alkhalikoi says, but if you still get an aborted install remove the present map from the unit entirely, along with any old .gma or .unl codes present in .system and try again. I'm more than a bit curious, why you would dl and put an unofficial map on your 1350LMT anyway, when you already have a lifetime map subscription?
