WildCamper;n22371 said:I use the old Go520 & Go720 models & TomTom explained they were not going to be supported anymore as the new maps would be too large for the device.
As these models have a SD card slot, their explanation made no sense.
I have just updated to the latest version of the Truck map using an 8Gb SD card & it works fine.
So don't give up on the older TomToms yet; especially if they are the models detailed above.
