The LMT does not apply in this case as there is no maps for the area I need. As mentioned, I have made the map (as an .img) myself using Mapwell. I will, however, try to clear the map temp cache. Thanks for the reply.
Hi guys I've made some maps with Mapwell that I would like to use with my Garmin nuvi 3490. I have yet to figure out what type of format a "car GPS" uses. Is it .img just like the handheld ones? I've tried to put a .img file on the memory card, but the map won't display. Also tried loading the map with Garmin Mapinstall, but the map does not appear as an option. Any help would be greatly appreciated.
