Having just updated to 4.4.4, I also updated two nuvi's and a Montana to CNNA 2015.3.
So I wanted to put only the Western part of CNNA onto the Montana. So far, so good. After starting BaseCamp, selecting the SD card in the Montana and asking to install maps to the device, MapInstall starts up and then from the partial/advanced install window I selected the CNNA tiles I wanted and left ALL the other topo maps on the SD card as LEAVE AS IS.
So MapInstall re-installed EVERY SINGLE ONE of my state topo maps, making a 5 minute process into a 60 minute process!:mad:
Why won't MapInstall do what I tell it to!!???
