Re: Backup camera and receiver upgrade?
most modern Navi equipped head units also come with rear camera capability.
For instance, I just installed a Pioneer AVIC 8200 in my '08, and now have every modern convenience: navigation, hands free phone, bluetooth, 2 USB ports and rear camera. Also have SD card data capability, and DVD/movie, and many of the vehicle OBD-II data things are available to display on the navi screen (tire pressure, mpg, things like that).
It is a job to run the new wiring (camera wire to the back door, back up light wire and parking brake wire to the head unit), but none of it is hard, just time consuming (getting the camera wire through the door grommet took the longest, but after untaping it and pulling the washer hose out of the way it was easy to thread the new wire and connector through, and then put the hose back in and re-tape). The more interior trim you remove the easier it is to do, but all of that up front is super easy to do (drop the glove box, remove center console and RH kick panel & scuff plates).
You'll need something like an iDatalink HRN-RR-TO1 for connecting the head unit to the car (if you buy another brand of head unit the number will be different), and an iDatalink Maestro ADS-MRR for the steering wheel controls. Both are easy to get through Crutchfield who also provides free technical support.
You will need a PC (not Apple) to program the Maestro, but I was able to get that done at a local Best Buy.
Now my 9 year old truck is just as "now" as any brand new vehicle is.
A handy way to upgrade your "in dash" Aux in (mini plug) to an Aux in (mini plug + USB), is with one of these:
I got mine from Sonic Electronix for $12.
