As A new member i hope to get some help!
I bought a second hand TT GO 500 and I tried to updated with TT Home.After a few sec. a message comes " Invalid Version Installed"
I checked the version and it's : App 8.413 (1237/090427) OS 311596 GPS v1.20, Boot5.5022
Map "westrn_and_central_ eur._2 gb v 825.2157
Please,any idea what to do and how can I download any other map ?
