Jvc kw nt3

Hi All,

Is there anyone who knows if JVC KW NT3 aftermarket navigation can be updated with fresh maps?
I have searched the web and the latest update I found was 2013.

Also I have seen that this nav uses Tom-Tom TeleAtlas Maps Europe JVC KW-NT3/30 E version 3.
Is there any chance I can upgrade with a newer TeleAtlas map?

Thanks in advance!
