Here are pics of the modified radio front panel.
The three position switch on the right selects: OEM data, ext VGA data, force rear camera.
The push switch is for selecting VGA input, AV1, AV2.
The rear view shows the mounting for the switch panel.
I determined that you really only need to have the use of one, the input selector switch.
The other switches set monitor modes so the remote takes care of that.
The tiny hole in the front is an LED that shows power on for the display (red) and also valid input signal (green).
The modified OEM radio re-installed.
The Mac Mini wired and installed (power supply is in center console)
The 5 volt regulator and breath mint box I enclosed it in.
The 5.1 decoder with the 5 volt regulator in circuit.
Now all that is left are software applications.
The newest part of this project is taking the OEM radio sound and running it through the system.
I plan on converting the OEM to TOS then using an A/B TOS switch to toggle between OEM and the Mac Mini.
I want to try to make it "seamless" so I may trigger the switch off the VGA select.
I am also replacing the Mac Mini with a more powerful version (late 2009).
Some parts came in so I finished this addition to the mix.
The video A/B select has a X/Y output so I wired up the "Y".
Makes for a nice (15") screen to watch a movie and listen to the 5.1.
My version of the 21st century "drive-in".
The IR remote control for the Mac Mini has a patch so the volume control will also work.
Now I have all the functions I wanted.
Replaced the hard drive in the Mini Mac with an SSD and it boots a lot faster.
Added more memory also.
Wired up the reverse sense and now the rear camera comes on automatically.
Hey! I must admit this thread is pretty cool, man.
I'm curious though: you said you upgraded the Mac mini with SSD and RAM...
What were the specs before the upgrade? How much RAM is there after the upgrade?
Thanks for the comps!
The Mini had a 240 gig HD so the SSD swap was a wash.
The Mini had 4 gig of memory and now it is 16, the max you can put in a 2009.
Whew, quite an involved install here!
Nice work, love the orientation of the Apple logo.
Great find on the 5.1 decoder, I want to run optical to the trunk instead of RCA's. Been a couple years since I first started looking into this, but couldn't find anything other than decoders for gaming headsets and they didn't work for chit.
