I have a multiple boot setup on my phone so that I can try new ROMs and easily switch between them. I installed TomTom on one of my ROMs and downloaded the map of Europe, which was saved to my SD card. Everything worked as it should. I then switched to another ROM, installed TomTom there, but when I tried to open it I got a message saying that I had no internet connection. I did have an internet connection. The same thing happened when I tried to install it on the third ROM. It is still working fine on the first ROM where I installed it.
Could anyone please tell me if it is possible to have TomTom working on all three ROMs, all using the same map that was saved on the SD card? I know that maps are registered to work with one device and cannot be transferred to another device, but it is the same phone, just different ROMs.
