I have used Fastactivate numerous times with a 730GO - no problem.
Trying to put a new navcore and map on a friends TT ONE is giving me a headache because I cannot get the device to accept the new SD card with NC/Map no matter how/where I use Fastactivate.
I guess I am missing something basic (and yes, I have looked at the guidance with Fastactivate before Tendriver tells me off!)
So any help would be much appreciated, thanks.
