Agreed. My '10 with nav has been great but for low to no-interest financing you could get a brand new I2, do that. There are plenty of aftermarket Navs that can be fitted in the dash. The OEM nav is nice but definitely not what I would consider a deciding factor as there are plenty of aftermarket units just as good or better. Plus, OEM nav discs are expensive, usually $180 to upgrade. I got a deal on mine for $110 IIRC from an offer they sent me, still too expensive.
