Try removing the faceplate and cleaning all the contacts.
Leading evidence: 'Clean contacts' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Clean contacts' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Yes thats it, the RDS/RBDS is the issue, when I dealt with this problem, I gave PCA the stations names and they contacted the offending stations and had one of them change their code.

Suggestion · Original poster
that if I manually set it to either station, it will stay but won't if I use the program buttons.

Suggestion
The same station had/has different Frequencies across a large area and the Radio would keep you on it using the strongest signal.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2003 C4S with factory CD/Radio. Just wondering if anyone has seen this in
any
car before. I've got plenty of local stations programmed in my radio and they all go to the station they're supposed to when I push the buttons. EXCEPT, I have two stations programmed to two different buttons and I can only ever listen to one of them at a time. For example, if I press the 3rd programmed station, it goes to 93.5. If I press the 4th, it will not change (even though that button was programmed to 99.7).
Here's the really weird part. If I am listening to either of those stations, it will randomly switch to the other station. Then sometimes it will randomly switch back. It's just so weird. It's almost like the radio just gets those two frequencies confused for whatever reason.
So basically I can't ever select to listen to either of these stations because I don't know which one I'm going to get. I
think
that if I manually set it to either station, it will stay but won't if I use the program buttons.
It's not a huge issue for me; I rarely listen to it anyway. Just wondering if anyone else shares in the radio weirdness.
If you program those buttons to other stations does it still happen to those new stations. also, if you program those stations to other buttons does it happen with new buttons. This way you know whether it is the buttons or the frequency logic that is the issue
Yea, I know of this problem, it has to do with the station sending out a broadcast code. I think you have to get the station to fix this on their end.
It been many years since I deal with this, but it stems from a feature that was built into the radio, mainly for Europe, so that you could drive across Europe and the radio would automatically switch to closest station sending out the same code so that you could keep same program on the radio even though it was coming from different stations/frequency's.
I know it sounds confusing but the same program is played across the country on different stations on different frequency's, more so in Europe, but in the US some stations playing "different" programs can be sending the same "code" unknowingly .Most radios do not pick up this "code", they only tune to frequency..
I had a feeling it was something like this because it seemed like it would change at exactly the same place on one of my normal routes, I'm guessing because that's a low spot for one of the station's signals. I'm going to continue doing some testing as others have suggested to rule out any contact issues but it would be crazy if that's it.
You mean this....? Was (maybe still is) very popular in Germany. The same station had/has different Frequencies across a large area and the Radio would keep you on it using the strongest signal.

Yup. It has to be RDS (Thanks Porschetech3 & Behle). I did a bunch of different tests today and no matter what it was only these two stations and it happens as I drive through different locations regardless of which one I set it to and how. Apparently there is no way to disable RDS handling on these radios so if two stations broadcast the same id code, there isn't much I can do.
Yes thats it, the RDS/RBDS is the issue, when I dealt with this problem, I gave PCA the stations names and they contacted the offending stations and had one of them change their code. I don't know if they would do it for you, or it would even be worth your trouble, they may not even know they both are sending the same code !! Rest assured your radio is functioning as designed.
