Aftermarket Head Unit and now NO am reception!
All:
HELP!
I recently installed a Kenwood KIV-700 which is a great single DIN receiver. I also have the add-on HD module (Kenwood KTC-HR300). Everything works great on the receiver exception that I now have NO am reception. FM reception works great and it picks up HD on FM no problem. I think I've done my due diligence here:
1. I have hooked up the power lead wire for the antenna from the HU to pin 5 of the black harness. This is a blue wire from my HU and I mated it to the Metra harness I'm using. The black plug in the car then plugs into the Metra.
2. I've double checked and from what I can tell, no grounding issues. Also, all other wiring works great (i.e. dimmer, memory on HU is fine after ignition is turned off, etc.)
3. AM reception was FINE with my old Becker CDR-220.
4. I have not tried the "AM antenna hack" listed on several boards because the AM reception worked fine with the stock Becker HU.
I'm at a loss here, guys. When I say there is zero AM reception, there is ZERO. Just a whining noise with a lot of static on every station. Again, from what I can tell, the amp antenna IS getting power.
This is a shame because it's such a great HU otherwise.
Any thoughts, tips, etc. are greatly appreciated!

It seems that the most likely problem is a defect in the Kenwood unit.

Sent unit back...will update
After more testing and logical deduction, this is the conclusion I came to as well. I just don't see how the old Becker CDR-220 AM reception is fine and nothing with the Kenwood. This was the case running the antenna through the HD Radio unit and directly plugged into the head unit itself.
The seller was really cool about doing an exchange. When I install the new one, I'll let everyone know how I fared.

AM signal quality really sucks anyway (consolation), unless that's all you have and live way out in the country. I'd probably listen to AM if I drove an old Ford pickup and drank cheap beer I'm assuming most Boxster owners listen to FM. Personally I like to stream commercial free, static free music through my iPhone instead of annoying yappy DJs and commercials
All kidding aside (Sorry to poke fun at you)... Sounds like your Kenwood is bad.
