Neil,
Thanks, could you please help again.

I installed the new 2014.20 Europe gmapsupp on SD card
I replaced the JCV file in the garmin device memory by the new one D3084110A.JCV.
It seams to work.

My question:
1) why during the boot device I do not see anymore the message for the new map (2014...)
This message was OK on 2013 map, is it because I deleted old JCV file ?
FYI, I clicked in the option menu the new 2014.20 map and disable the old one (still in the device)

2) how to check the new 2014 Europe map compare to a previous version. Is there a web site showing new roads or round about ?
Thanks
