Hello, am playig with my hubbys tomtomGO 700, bought a map update and now have come hugely unstuck trying to update the device. It says there is not enough free memory but I have taken off eveything that the HOME software said was on it (copied to computer).....what's going wrong - he's going to kill me when he finds out.... Then my device disconnected itself and when I restarted HOME doesn't recongnise my device with full serial number.....and thinks it's a different one - help! what have i done!! I am using Vista and it did ask to scan device - so I did that...
