This morning I hopped in my car and tried to change the station using the Tune/File **** and found that it didn't work.
The **** appears to turn fine with nice, soft clicks like normal. I didn't have time to fiddle with it then (ended up using the up and down buttons under the Volume **** to get to the station I needed).
Before I got home, I looked up this issues on the forums and found similar issues reported with RX 3xx owners. Some said on those threads to try to pull the negative terminal of the battery and try to check the radio fuses. So when I got home, I pulled the negative terminal and checked the RAD NO. 1, RAD NO. 2, and RAD NO. 3 fuses. All the fuses were intact but the RAD NO. 3 fuse under the passenger seat had marks on the connector as if it was burned (see attached pics). I ended up getting another 10 Amp micro fuse to replace it and reconnected the battery.
Once I fired up the car the Tune **** was able to turn to another station before then stopped working. Which makes me think that something is holding it up, but I'm not sure about it. A note to add was that behind the fuse cover that is under the passenger seat was some sort of white and blue powder that covered the inside of the cover and several of the fuses.
I also have checked the Faulty Stereo?
thread and I'll be trying to push in the bottom radio panel where the **** sometime soon. Anyone has any ideas on what would cause this? Thanks for reading and any input.
For the people that feel like it's TLDR, here is a condensed version:
Started the car in the morning, tried to use the Tune/File **** to change station. **** did not change stations.
Looked at threads on the forums and found similar issues with RX 3xx crossovers with possible fixes.
Got home, tried fixes to no avail. Noticed a fuse that had what looked like burnt connectors, got a replacement fuse installed.
With the car on, the Tune **** was able to change to a station and then immediately stopped.
