09+ CIC I-drive difference between each model years
I'm wondering about 09+ I-drive system updates/differences.
Mainly 09 vs 10 vs 11 vs 12.
How are they different? How are they updated from each year?
I have 09 I drive, am happy with "new" HD system with upgraded multi buttons on the center console.
I don't use bluetooth, satelite or HD radio, I don't use "connect drive" thing that lets you use phone messages facebook and all...
All I use is Navi, various car set-ups (Mdrive), CD and Aux.
I found out my 09 can upgraded to the software/map to latest spec.
Should I upgrade to 2012 i drive spec?
