Well. It works great!
1) remove bezel around radio...It just snaps off.
2) remove 4 10mm bolts to remove the touchscreen form the dash.
3) unhook all of the factory plugs by relaesing the locking tabs and gently pulling the plugs out.
4) at this point I took the head unit to my workbench (kitchen table) and saw that the module has posts that line up with holes on the touch screen.
5) remove three phillips screws each side to take the stock mounting "ears" off.
6) snap on the new brackets (PN#591-00140)
7) if you put them on correctly (they are marked right and left) you now can replace the stock mounting ears over the new mounting plates.
replace the 3 phillips screws each side and install the two that came with the bracket into the module...this makes 5 philiips screws each side.
9) plug the new jumper cable between the boxes
10) make sure the cable attached on the module is plugged into the head unit. (see purple marked photo above).
11) Now you are ready to put the headunit back into the car.
12) At first I did not know where to mount the GPS antenna...then I decided to place it just below the dash on top of the defrost vent tube. The kit includes a self adhesive metal plate that I stuck on there. the antenna has a magnet mount but I used some of the included foam tape and clips to secure it. Also, I removed the upper dash bezel and the gauges for access.
13) replace the wiring harness plugs. They will only fit into one slot, so take your time and make sure the plug matches the socket.
14) *NOTE* both antenna wires will now plug into the new module. ( see purple maked photo above) Make sure you push the connectors on until you feel or hear a positive "click".
15) Replace the four 10mm mounting bolts.
16) At this point I checked the touch screen for functionality. It took several minutes, but eventually it booted up. I have read other places that you may need to reset the touchscreen by holding the audio button down and turning on and off the lights three times. I did not need to do this. Do not be alarmed if the navigation unit does not know where you are at first. You need to drive a short distance in order for the nav to recognize where you are in space.
17. Replace the gauge panel and the remaing dash bezels by snapping them back in place.
18. You're done! Have a cold beer and think of all the money you saved by doing this yourself.
I am extreamly happy with this mod.
