Okay. One of the biggest mistake of my life was having a local audio store installed a Clarion radio into my 00 VW Golf. The car's computer diagnostics ran through the stereo and instead of using a wiring harness adapter, they just cut the wires and started crimping. ODB connector gone. Long story short, I didn't discover that for a year or so and it messed with the car's electrical enough to make the car exceedingly flaky.
So I got me a Taco.
Does the 07 standard stereo have any of that kind of interactivity with the ODB II port and computer control? Or is it just a separate electrical system?
