Wha? 8th gens had them as well... Aussie coupes had them. College Hills made them available at one time.
Here is something... There is more stuff in your 8th gen than the 9th gen. Though you must have EX-L and be 08 thru 10. Later 8th gens started getting less.
Something the 9th gen does have... no aux power with the ignition off.
You can install an 8th gen sedan rear vent to a coupe. That would be the 8th gen equivalent to 9th gen.
Everything else with the 9th gen is 9th gen specific. Smaller car and physically different interior as well.
Somebody should post 8th gen stuff that 9th gens don't have.
Also for peeps who don't have Navi, tablets are a dime o dozen. There was a thread on installing a tablet for all your Navi needs, and does a better job at pairing, syncing and media play without all the issues. My bet is a Venu Pro 8.0 and a selection of paid programs for the ultimate NAVI experience. Proscan or ScanXL Pro beat any Andriod app like them hands down.
