My problem with my nav 4.Navcore 22.100 patched and worked until this day. I deleted old map and installed new 1110 map. manually updated meta code to meta.txt. Now tomtom says no map available. Tried with old map 1105 same problem. No maps available. mstms menu sees all maps.
Removed patch and installed it again. No luck! i really dont know how to get it work again.
