I have a TT 740 running truck Navcore and maps on an Micro SD card and it works a treat. Wife has just bought me a TT Start 25 and I cannot get Truck NavCore or maps to run on it. When connected to PC, I cannot see the drives on my device and if I put in an Micro SD card in my start 25, it formats it, then when I connect the card to my PC it says its full. Any help would be appreciated.

And there is a reason why truck compatible devices are not sold for 50 bucks brand new....
