2013 tacoma only 2 fm stations come in on a scan search

Radio is what came with truck.
2013 tacoma.
bluetooth works fine.
only 2 fm stations come in good.

seems worse when vehicle is moving

 

Has it ever worked?

 

Try unscrewing the antenna and cleaning up any corrosion/dirt build up then put it back together

 

Install any aftermarket items recently?

I lost radio after putting in a cheap dashcam. Turns out the wire harness was causing interference.

Pull the fuses on any aftermarket, then check the antenna connection in the back of your head unit.

 

Also check to see if the antenna is actually connected to the radio and it is not cut somewhere.

 

as far as reception on fm radio. it has never worked goid since getting the truck.
i unscrewed antenna and blew out a bunch of crap thst was in tgere but it didnt seem to improve anything.
literally only 2 station on fm come in clearly as it should.

 

i found a thread on here to test by disconnecting at connection behind side pillar and try using a wire at connection. that didnt seem to improve anything either.
When i put connections back together signal definitely better but still only 2 stations come up on fm scan. weird

 

The corrosion starts and is primarily under the black cover of the antenna base.

 

so i am going to try and fix this today. i have the day off.
im hoping i get get the castle nut off with vice grips. i dont want to get the drill out around my hood.
i have all the parts im just waiting on the fender liner clips. i was just going to break them off and replace with new ones.
do i need the clips to hold the liner on or are there bolts that hold it on until my clips come in.

 

Sub'd for the outcome. Im 99% sure Im going to have to do this at some point

 

The antenna may also be disconnected from the back of the stereo head unit. Sometimes those are a pain in the ass to keep connected when putting the head unit back in.

 

i checked that just in case and it was connected.

 

so i started working on this but im going to need the clips. they arent coming in until saturday.
i did manage to get the castle nut and bezel off. used a 3/8 drill bit. then went a size bigger and went slow at an angle and it all broke off

 

well then

 

Just curious...are you still getting 2 FM channels with the antenna removed?

 

i get one that comes in a bit still. especially when stopped and not driving

 

Pretty clear you found the problem.

 

Taco OEM radios are not known for longevity, often only last 8 to 10 years before they start having problems. Rather than spend hours and hours of your time trying to fix the problem on an old radio that’s probably going to crap out anyway sooner than later, you are better off biting the bullet and getting a new radio. You can get a decent replacement for a decent price. I’d rather spend my time fishing than messing with an old malfunctioning radio..

 

A new radio will still have the antenna plugged into it.
OP has a bad antenna base mount. A new radio will still result in only 2 stations unless the base is fixed.
I wish the 2nd had a shark fin like the 3rd Gen. They don’t have this issue and you don’t have to take the antenna off when going through a car wash.

 

after you fixed yours did you put any silicone around the base? anything to prevent it from having this issue again?
