Thread: 3790 additional maps on SD card

Hi
As I have a 3790 with only 1.73GB of memory, I have put the full Euro 2014.20 map & corresponding Jcv file (D3048120A0 ) on the SD card

My intention was to have the "Voice Command " available on the unit for the UK ( apparently does not work with UK & ire only map )
Both maps show under map info ,but when I untick the UK & ire map and then check the voice command I still receive "this feature is not available for England " , back to the map info and the UK map is shown as ticked ,it appears to re-enable itself so I think that is what is still stopping the voice command problem ??

Also the Jcv file is on the SD card ....Garmin/Jcv but not showing photoview ?

Any ideas ....
Regards

PS Jcv is located ....SD Card/Garmin/Jcv/D3048120A0 is this correct ?
