MrBlueSky Posted September 14, 2016 Report Share Posted September 14, 2016 I have 2015q2 maps on 3.0 firmware Is there anything better I can do ? Is it worth 4.0+ firmware ? custom ? It would be nice to have real speed on the nav, Diafta mod for this ? If you go to 4.0 what compatibility with maps ? Just update and everything still works?
