Long time lurker but recently deal with Mike -
@Mpgrimm2 and my 2013 3500 truck had a factory 8.4. Wanted AA so got a harness and radio from Mike. Support is well worth it and the packaging was top notch. Solid guy and actually tests everything first. I got a "new" radio and Mike spent some time and money to make it ship safely and securely. the packaging was on point. For something this expensive that is VERY nice!
So far the only issue I have is the Chrysler 200 hub won't fit all the way in on my jump seat. Mine apparently has a different metal bracket than most that gets in the way. Haven't cut it out as of yet. Pic attached if anyone has a jump seat, check that metal first.
I must say screen is more crisp and audio seems WAY better (more bass) than my factory Harmon unit. Maybe more power to the amp? Maybe placebo.. Not sure. This isn't a cheap upgrade. But absolutely worth it and I'm very glad I met and got to support Mike in what he does.
