kgerry Posted February 2, 2011 Share Posted February 2, 2011 I am curious if anyone knows what the changes are from V5.1 (i think my 06 came with Gen 4 V5.1) to V9.1? are they simply mapping or are there firmware updates for the system as well.... i find the screen layout fairly archaic compared to the aftermarket units i sell....
