    My 2008 Roadster has a JVC KD-NX5000 Nav unit. The AM radio reception is almost worthless! All I want to do is listen to the local news on the AM radio. I saw someone mentioned an aentenna booster that Tesla has installed on some cars. Even with the booster, one owner said the reception wasn't great. Has anyone found a way to get good AM reception?

    Nope. Stopped using AM in the early seventies. Stopped using FM in the mid seventies.

    Ah, a wise guy! (Curly of the Three Stooges) :biggrin: I don't know about up there, but unfortunately down here in Los Angeles the only 24 hour news station is on AM. I plan to use the new car as much as possible as my daily driver. It's going to be a disappointment if I can't get decent AM. The static seems to be the worst during regen. If we can put a man on the moon, there must be a way to fix this?

    It might be possible to simply relocate the antenna...? I know the key fob antenna originally had horrible positioning in my Roadster, and simply relocating it had a huge effect on range.

    AM will not work with that JVC unit. I use stitcher on iPhone and it's a better way to listen to news. You can start from begging of stories, rewind, forward, and pause and resume where you left off. I did the double din upgrade to Alpine unit + antenna upgrade and AM works. However, I still use Sticher for news.

    Thank you guys! How about Sirius or XM? I assume they have reception just like FM?

    Apparently, they are not what they once were, though they might be okay for news.

    This is a valid point that has bugged me for a long time. The art of designing radio receivers has come a very long way since the crystal set days. A cell tower can pick out the 0.1 Watt signal of a single handset over the din of thousands of others on the same frequencies at over a mile a way...yet a 50,000 Watt AM station being the sole transmitter on that frequency in a 100 mile radius still cannot be picked up on "modern" automobile radio sets worth a damn.

    Probably has a lot to do with the fact that cell phones don't use the primitive AM modulation format...

    Art it's pretty much the way it is. When I got the car I wondered why they bothered even putting in a radio if it was so useless.
    There is a antenna booster TSB at the service center. I got it done recently but AM went from worthless to terrible. I can listen if the car is stopped or at a fixed speed. Makes for some weird driving decisions.

    It looks like they rerouted the radio antenna as well. I didn't notice it before but now I have this wide rubber strip running up the passenger side front window column, I didn't notice it before. Very odd and unclean way of running it for a top dollar car but I guess they're trying their best to get an extra station or two.

    Does anyone know where the original antenna was routed? I many take my dash off and just stick that ugly looking strip in there. Was really looking for the booster upgrade but would have liked to skip on the antenna mod.

    I had a problem with the AM radio when I first got the car. I complained several times about it and Tesla did service it somehow to make it better a couple years ago. Now the AM is only garbled when I accelerate. Once I get to a constant speed it is ok. It seems like there was a lot of interference from the engine and now with the change the interference is only there when you accelerate. They may simply have changed where the cables were running. I also do have Sirius radio which works like a charm. There are no interference issues with that at all. However, I still listen to AM a few times a week for sports broadcasts or sports radio.

    I complained when I first got my car and they re-routed the antenna which improved it some. This was before they had the official TSB so they didn't install a booster. I quit using it and subscribed to Serius XM which works pretty well but I've had slightly better reception in other vehicles.

    Do any of you guys know where the aentenna is located and the route the cable runs as delivered from the factory?

    I got the TSB fix and AM reception is so much better! Now I just get some static when I go under bridges or something, otherwise it sounds like normal AM radio (which is mostly crap anyways). FM reception is great and fortunately most major AM stations have a channel on FM now.

    Thank you all. It looks like our best news radio station in LA had an FM channel they used to broadcast on, unfortunately it is now music. My car is out of warranty and I am the second owner. Does anyone know if they would install the aentenna booster or take care of any TSB items at no charge?

    That's because you need to design a new protocol for both the transmitter and receiver to get big improvements.
