    Just put in a new
    $1,000 Kenwood DMX1037S 10.1" High Definition Car Stereo Receiver with Capacitive Touch Panel
    Kenwood DMX1037S in a 2020 Platinum. Everything works except FM/AM. I get ONE station which is located in my town, in HD radio, but not a single other station comes in at all, and there are plenty. I've pulled the unit 3x to check the antenna is plugged into the back of the HU and the correct adapter is being used. GPS and SiriusXM both work great.

    I was gentle but unless there's something wrong with the adapter harness or I somehow pulled on the antenna wire going to the factory antenna and it came out of the antenna on the other end or broke the wire, I just can't figure out WTF is going on?

    What are my options? Do they make aftermarket FM antennas for 2020 Tundras with hidden antennas?

    Can't tell but is the blue wire on that adapter hook up?

    Everything I've seen online about the Tundra has said no power to the antenna and we don't use the small blue wire.

    Guess I'm the only one who has ever experienced this? I guess my question is are 2020 Tundra antennas powered?

    Have you try hooking it up to power and see if it does anything?
    Running out of idea.

    Alright...I want to clean up my harness too. So I can tap the yellow 12v wire to power the antenna? Also, since I'm using RCAs for front/rear/subs I can just get rid of all of the speaker wires....correct?

    Also, in the picture above in post #1 it looks like there are TWO wires (1 large and 1 small) on the factory harness...my guess is the small one is for power.

    Yes, you can omit the standard speaker wires since you are using rcas. You can tape them up, make sure the ends of those wire are capped, either with tape or shrink tube. No exposed ends.
    Tap the blue wire from photo in post 1 to an acc wire. If you have posi-tap, that would make it easy.

    You can also use the Blue/white wire on the maestro harness for power too if you want .

    It's even easier...the Kenwood harness has a dedicated wire to power an antenna labeled Ant Cont. Thanks for your help!

    No, but they switched styles in 2019. I do not have a traditional vertical style antenna. I believe it’s hidden in the shark fin now.
