I'm hoping someone can assist?
I'm using a Garmin Avtex Tourer Three for Motorhome navigation and about three weeks ago I installed the latest Map Update (CN Europe 2026.20) and ever since then it only shows a very small number of major roads.
I have tried a factory reset and there is no removable memory card and I cannot find a way to reinstall the maps in case there is a file corruption.
The install of the maps appeared to complete successfully.
Any suggestions as to what I can try next appreciated (also hopefully I put this under the correct forum category)!
Thanks in advance, Andy
