Well I tried a few decks and had to return them (it felt weird returning a radio with like an inch missing off the harness wires, although store staff assured me that was ok) and almost gave up...I even put the OEM radio back while I figured out what to do. The other reason was that I wanted to mount my radio scanner at the same time in the 2-space slot, no better place for it. I thought yeah this technology should be perfected by now and every unit should have a perfect tuner. Well no.
I eventually settled on the
JVC KD-R400 which had USB and Aux but not too many other features that would induce noise. Oh, and low cost.

You bet it was weird demanding a quality AM tuner at electronics stores. People gave me weird looks and one person actually finally had to ask WHY. Well a lot of my favourite radio stations are from small rural towns. And the good conductive soil makes that easy to pick up. If you live in a mountainous region, well, physics still prevails and you can't get much even with a great tuner.
The evening I got it installed I was quite surprised because I was picking up stations from all across the prairie provinces... one of the
farthest was from Manitoba.
It also mutes the audio when it detects mass amounts of 60Hz interference from power lines, which is nice. It also has a better, more parametrically adjustable EQ which I like, although that's probably just me again with my weird audio dynamics preferences.
The stock Delphi radio is acceptable in terms of distant AM reception but isn't as good at rejecting the strong local stations on adjacent frequencies. It's sitting on my shelf at home and I built a shrink-tube wiring harness and use it as a radio because it's still working properly. Thing runs really hot though, insufficient heatsinking. Or they expected it to be mounted right next to the air conditioner or something.
