I have a Start 50 with a 32GB sd card. I can download & transfer one of the smaller EU maps to either the SD card or the units internal memory. However, is it possible to put the Northern EU map on the Sd card and say the Eastern EU map on the internal memory. AS TomTom Home does not support the Start 50 I can only use TomTom connect and I cannot find a way to do this. Any suggestions would be appreciated.
