I don't have much planned in the way of mods. Is there a navigation system that fits nicely in place of the stock radio? Any proven mods to increase gas mileage?

Looks like a 1.8L 4 speed then. I got it from a dealership and the previous owner had left maintenance receipts in vehicle. All of the receipts (from the original dealership) indicated it was a 2.4L. No worries, a bit better gas mileage I guess.

Well... the shifter goes "P / R / N / 3-D / 2 / L and the paperworks says 2.4L FWD. The top of the engine says Dual VVT-i

Quick question. How can I tell if a 2009 is a 4-speed or a 5-speed? Thanks
