So I'm pretty good with electronics. The dealership is not.
Has anyone heard of a Pioneer AVIC-Z140BH causing interference? Electrical bonanza!
Next step will be to just bite the bullet and go to a specialist who will pat me on the head and tell me what I did wrong but any input/anecdotal experience you guys might have would be appreciated.
Just for reference, I installed a very similar setup in my '09 and had no issues.
