Dear All,
I've been having problems adding additional CN map in my Nuvi 4592LM device and SD Card. It always pop up a display of saying "Maps are corrupt and cannot be used. Go to w.garmin.com/express to download the latest maps." And I had used this same map file in Nuvi 3790 before with no issues at all.
My Nuvi 4592LM has 3 preloaded maps already, consists of CN Singapore Malaysia NT 2014.40 (gmapprom), Malsingmap 2014.30 (gmapprom1) & Malfreemap 2014.30 (gmapsupp). And the other additional map i want to add is CN Indonesia 2014.40 here.
Any advise would be appreciated, thanks in advance![]()
