The Pioneer AVIC is OEM in the STi Limited, but a different Pioneer model. Any ideas on how the two differ? There are mixed reviews re: the AVIC in the STi.
Depends on your model year.
My 2011 Forester has the PIONEER NAVIGATION/AUDIO SYSTEM (AVIC U310BT)

http://www.subaru.ca/WebPage.aspx?WebPageID=16428&WebSiteID=282As for the U310BT, I wouldn't wish that hell on anyone, nor would I ever pay for it, and nor will I buy back my Forester after the lease because I hate that damn thing (and I don't do after-market). Ok, the 2014 Forester's fuel economy gain is probably the bigger drive to not buy-back my current Fozzie.
Back to the Pioneer systems - they have some interesting functions, but the U310BT Nav itself is AWFUL (wrong directions, slow input, no autocomplete suggestions, doesn't understand most addresses, etc). If this one, or any of the other Pioneers are similar, I would steer clear. I should hope that a name as big as Pioneer would fix those, and that'd explain why the 2012 models got a different unit.
