A friend has asked me if I can install an updated UK map onto her old TT One (3rd Edition) as I have helped out in the past. However, this is a while ago and I've forgotten what to do!

I tried connecting to TT Home so that it would put latest Navcore on, but, this told me it was an obsolete device and go away and buy a new one!

The info from the unit tells me....
  • App 8.562 (438269/091014)
  • OS: 331278
  • GPS 1.20
  • Boot: 5.5022

Is the 8.562 the Navcore and can anybody tell me if I should be looking to put a different version on or will that allow me to update the map?

Thanks
