Hello all, new to the forum here and having a hair pulling frustrating issue with my head unit. Let me just say, I was raised in a software engineering and computer background and have soldered numerous units in my years. I recently bought a pickup with a Pioneer AVH-2600BT head unit already in it. It was put together cheaply as a owner was a younger kid, with butt connectors poorly holding harness cables together. I ripped it apart, got a new connector and harness and resoldered it.
The issue I am having currently is my unit will lock up on bluetooth when connected to my phone, freezing the now playing display on my head unit and then the audio feed cuts out and is replaced by this incessant beeping. The issue is intermittent and will often fix itself in like 5 mins or sometimes not during an entire commute. Video incl. Phone I'm using is an Samsung Galaxy S10 and trying to stream from spotify. These issues started about a week ago. Also, I had my friend connect her iPhone and her spotify via BT and she had no issues with it for the hour we drove.
I've tried impairing, repairing, restarting my phone, scoured forums, I can't find any leads.
