I'm moderately experienced & competent at updating 3 different models of Tomtoms.
However I'm seeking advice on updating a friend's unfamiliar model. I suspect the Navcore and map are pretty archaic.
The following summarises the information which is readily available:
Model: ONE v4
Serial no.: AKX** AJF**
Navcore: v 6.560
Maps: Western Europe v 660.1256
App 6560 (7914/061211)
OS 1713
29MB RAM
GPS v1.21
Boot 5.05
the device has a SD slot but there is no memory card fitted.
What update of memory, operating system and maps would you advise? And in what order should these be carried out?
