Personally I am thinking about the
JVC KW-HDR81BT for $230. It has a lot more functionality vs the stock head unit. Plus it looks like you can get it to match with the current led's in the car.
Sorry I don't know too much about cost to install. What you will need for your install -
- Some steering wheel control unit like the Metra
- Bigger speaker wire. I'd go for 14g. Shouldn't be too expensive for the short distance the wire has to travel.
- Besides that you'll just be paying for any soldering and wire running. If you're not installing an amp it's really pretty straightforward.
You probably won't need a Dash kit to mount the unit, but it may also leave you dash unfinished.
If you take this route you'll have to sacrifice the camera idea. However, I think looking at a rear-view camera on a 4.3 inch screen even with 20/20 vision will be a bit of a debacle.
