Hi, I have over 100 Tomtom devices. 17 of which all started malfunctioning in the same way at the same time. Updates simply go around and around and around. Ive tried leaving devices updating for over 3 days as suggested by Tomtom but to no avail. They then suggested that I dont connect the devices for 4 weeks, the Tomtom servers would automatically reset and the problem would be resolved.....NOPE! I had a guy from Tomtom log onto my PC who promised further technical assistance but that was the last I heard. After an hour and a half on hold today I ended going back to square one and being asked to do simple actions like a soft reset and the operator just wouldn't listen. It all seemed to begin when Nav 4 was launched. I know that on some devices I had full size USA maps saved to the device which just about squeezed onto the onboard memory. However, when nav 4 came along I wouldn't have had space to install this onto onboard memory as there was no free memory. I attempted to delete this map and install a smaller one so that Nav 4 would fit but, because I didn't have Nav 4 it wouldn't let me! Please don't direct me to generic basic instructions - there is a real issue here that is stopping 17 of my devices working and it's been going on a year now. Please dont direct me to customer services either as they can only do the basics such as cache clearing and I've done the basics on every device multiple times. Please don't direct me to the Repairs team either as at £100 per device to fix a problem that is an issue Tomtoms end isn't particularly palatable. THIS NEEDS SOMEONE WITH SOFT / FIRMWARE KNOWLEDGE (PREFERABLY BASED IN THE UK) TO RESOLVE - PLEASE ANYONE ???
