Prius (Gen 3) :: FM Radio Frequently Loses Reception After 12V Battery Changed
Sep 3, 2015
Recently, we had to change the 12V auxiliary battery on our 2010 Prius IV. Everything went smoothly and the entire procedure took less than 20 minutes. We thought everything was good, until we turned on the radio.
Since we changed the 12V battery, the FM radio (which is part of the NAV console) has great difficulty keeping any station tuned. Before changing the 12V battery, we could drive around and listen to our favorite FM radio stations; now, the radio frequently loses reception, and our music frequently gets interrupted with static.
It's been a couple months, and the situation has not improved. We took a look at the antenna, and nothing looks out of the ordinary. It seem odd that changing a 12V aux battery would cause this problem, but we have not made any other changes (not even an oil change) for several months.

Having issue with XM Radio reception? My 2013 RX 350 loses signal with even minor obstructions. This is my second RX with satellite radio and 5th car and this model is terrible. I have driven behind friends with 2015 and 2010 models comparing when signals are lost and mine is significantly worse.

So I just installed my Pioneer 4400BH - Took several hours and all went well - EXCEPT - no AM reception after I installed the radio. FM seems fine.
Two possible guesses:
1. Did not push the antenna connector in far enough.
2. Gen 3's use an antenna amplifier. I did not think that Gen IIs used on so I did not connect the Power antenna lead to anything.

I'm experiencing issues with the radio when I change from AM to FM. If on AM mode and I go to audio button or on Steering Switches and push FM, it switches to FM reception (get the radio station on FM) however read out on the screen still says AM and all the presets are in AM mode.
On the reverse from FM to AM same occurs.
Is this a software issue?

I have been noticing a more frequent failure in my XM radio. I sucked up the extra $2000 for the GPS and use the XM radio every day, but lately, the radio cuts in and out or does not come on at all. I have to restart the car and then it will come back. The FM and AM don't fail but the XM is failing more and more frequently. My problem is it will be very hard to recreate since it only does it every once in a while.

Reception on the FM radio is not very good unless you are tuned to a local station.

For years now my AM radio doesn't get reception. Like there is no antenna. FM has always worked fine.

Have a 2010 Camry SE. Camry was broadsided in an accident and ever since radio has not worked properly. Radio was replaced by Toyota dealer with a new one but still same problem. Stations fade in and out like receiving weak signal. Is it possible that something connected to the antenna system was damaged in the wreck?

B5 03 Passat Wagon - I am having a problem pulling in am reception on the radio. I am getting significant static. When I remove the antenna mast, I get no reception. When I put it back on, reception returns but has static. Static gets worse when I put my had on the antenna mast and resolves to just regular static (along with radio program) when my hand is take off. Non existent reception when going under underpasses, drive through windows, or near power lines.

I just purchased a 2009 gs 350 a few months ago with 40k on it fully certified. I quickly noticed that most of the fm radio stations were static even local ones that I usually listen to all the time. Some stations would go in and out of static but too annoying for me to deal with. Ive tried turning random things on and off to see if it changes the reception but nothing works or makes it worse.
At first I thought I'd just deal with it, but then I realized how much radio I actually listen to. So I brought it to the local lexus dealer a few weeks ago to see if they could fix it. They replaced the head unit once with no success, so they ordered another one and replaced the original with it. They had the car for two weeks and when I picked the car up they said that all the stations come in except a couple.. Turns out it seems to be exactly the same as it was before, maybe slightly better. I want this fixed completely with no static at all especially since the car is certified and most things are covered.
I think it could only be one of three things the head unit, the rear windshield (where the fm antenna is located) or the wiring in between the two. Since they already replaced the head unit twice I think its safe to say its not the head unit even though they said they tested it somehow and that's what the problem was......

Noticed poor FM radio reception in 2012? Mine seems to just barely fade in and out. It's not terribly noticeable, but definitely happening. It's frustrating when streaming Bluetooth actually sounds better than the FM radio reception! I'm wondering if it's a problem specific to my car or if it's an issue everyone is experiencing.

Does the XC90 have a very weak radio reception? Some of the FM stations that were normally very strong in my other cars were weak at the XC90, and some of the AM stations that were normally okay got no signal at all at the XC90. Is there anything I can do to boose the radio reception?

I have an '05 Camry XLE with the in-dash touch-screen AM/FM CD Nav system. On random cold days I seem to lose my radio reception. When I turn on the radio I receive a lot of static with break-through talking or music. I've tried to change stations using the touch panel, the steering control as well as the manual tuning dial and I still got static.
I've driven to work ~40 minutes and most of them were filled with static and some break-through talking (not of the station I was tuned into though). The last couple of minutes of my drive I did get a station that said it was 98.3 but I was tuned into 95.5. No matter which station I dialed in I still received the 98.3 station.
It seems like the antenna or something in the radio was stuck or frozen. I drove the entire time with the heat blaring on feet/defrost and rear defroster on thinking it might warm something up but that didn't work.

I bought, new, a 2012 Camry back in 2012. I got the satellite radio option. The reception with satellite is horrible. On the clearest of days, I lose signal all the time making it useless trying to listen to it.
Yes, I understand vegetation can hinder reception. But, it shouldn't to this extent. Not long after I bought the Camry, I purchased a 2010 Ford Fusion. It, too, had satellite radio.
I think, in the 2 years I had the Fusion, I lost signal 2 times. On the cloudiest, foggiest, snowiest, and raniest of days, the Fusion never lost sat signal.
I had the dealer check out the system and they found nothing wrong. I've let my subscription to Sirius expire since I can't even get a decent signal. Is this typical of the satellite radio with Camry's???

I see this was discussed back in 06 but not resolved. Maybe more owners have had additional experiences with this.

The symptoms are: HV Battery loses almost all charge over night. Sometimes it won't start. HV battery loses charge fast while cruising in the city (I used to see it getting green at the highways with cruise control and now it doesn't happen). Red warning light goes on randomly.

I have a problem with my central locking, I changed the battery in the fob but it won't lock the car, if I lock with the key the fob will unlock the car. When I press the lock button there is a clunk-clunk as if the central locking is working and I can hear the noise in the doors and the boot but nothing happens. The battery was totally flat and I haven't been using the fob for a long time but I seem to recall it used to lock.

Does the 12v battery need to be changed on a regular schedule? There are many articles on "how to" but could find no info when it is needed.

Just changed out my 12v battery in my 2008 Prius, I found water in the battery compartment. There have been heavy rains this past weekend but it should not have entered the car.

I tried a few used batteries I had laying around, so then I ordered the exact battery that was in the fob, Panasonic 2032 and it still doesn't work. The car has always sensed my hand at door and I still don't need to put the key in the slot. I can just push start, but the lock and unlock buttons don't respond.
I've read that the red light should come on when the buttons are pressed, and they don't with the new battery so the new battery is probably too weak.
