Hello,I do not know if I am writing in the right place but I think that many of us will take advantage of the information.
I have a old GO730 that works like a charm and I mainly use the Italy map. Navcore is 9.541 . I use TTactivator and I usually select "high-level-u" maps but these maps have no meta codes in the last 4 editions (about 1 year). Is there any diffent map version that works on 9.541 navcore? Currently TTactivator propose me 1130.12304.
Thanks alot for your support.

You can use NAV3 maps...the chart above tells you which one to download

Download a "nav3" map instead of "high-level-u", and use the "Optimize_nav3" tool to convert the dowloaded map into a compatible nav2 map for your old device.

Thank a lot! Where can I find the "Optimize_nav3" tool ?

Hello, about Rider2 ...
This month, my old Rider2 runs a 1130 map (Nav3).
Its SD card is large enough, I don't need to reduce the size through Optimize.
