Carminat tomtom Live looping on start up
I recently upgraded my Carminat to map Europe 890.4222 (size 2381MB) but when I put the memory card back into the car the navigation system goes to the start up picture for a couple of minutes then shows the hour glass then back to the picture and seems to be stuck in start up. This loop continues and the system never starts up properly. When the card is removed, the screen shows the no card available screen. Has anyone seen a similar problem. I have map updgrades so should I reload the map?
