I've upgraded my TomTom One V3 to 4Gb MicroSDHC internal card (in adaptor).
What i'd like to know is, does anyone know which of the wires requires a switch so i can switch between original internal memory and the new SDHC card? The link wire CD-1 doesn't seem to work
Any Ideas?
Cheers

Bounce.....Anyone.....anyone....Beuller....
I can tell you that it's not Pin1 CD, or Pin4 VDD, or both 1&4 together :-(..... still testing

As I said I'm not 100% sure but pin1 and 2 (bridge them first) or pin 7 should be able to disable the card.
But I really think it would be nicer to be able to acces the card from the outside.

CD should be the right pin to tell the device an SD-card was inserted. Mine's rebooted when I pulled that pin to the GND, but still booted from the internal memory.
thread where I describe more details, last post
