I'm trying to install new maps on my Nuvi1350 with mapinstall but not enough space. I want to uninstall old maps (Citynavigator 2012) to make room for 2015 version. How do I do it?
You don't. By a SD card so the maps can be installed to there. Express will then delete the old files off your 1350 and install onto the card. If there was room on your 1350 to fit the new map once the older maps were deleted that would have happened, but it sounds like even with the old maps deleted there isn't enough space.
Incidentally you mention MapInstall, as you've posted in the Express forum I'm suggesting you use Express.
