Looking for a unit *Help

Don't bother measuring...you most likely won't have to worry about the size of the opening in your dash. It's standard double DIN. Practically all models with 6" screens and 7" screens will fit with no alteration....the 8" Alpine being the notable exception. The big difference (besides screen size and price) is that 6" screens usually have larger physical buttons and a rotary volume knob while 7" units are almost all screen.

You probably won't need a traditional AUX input as most NAV units have dedicated USB connections for iPods and iPhones.

Your limiting factor is most likely going to be your budget, at least if you plan to buy from a reputable source/authorized dealer. You're going to be hard pressed to find a unit with baked in NAV at $500...off the top of my head I can't think of a single unit that I would recommend. Most decent units range from approx. $700 - $1300. They can usually be had cheaper at places like eBay, Amazon, etc., though there is a good chance that any warranty issues won't be honored.
