I called a local car audio installer here in Atlanta GA and they will charge me $50.00 to solder. Can You post a video on how to remove the case of the unit to get to the cpu board?

Do you know if the same unit in Amazon USA right now has the fixed board?
I want to buy similar one for my other car and I was wondering if I still have to follow the instructions to fix in unit I will buy next week.

Sometimes I have problems to change (with long press button) radio frequency (not memorized station - short press button) with my Pumpkin CN10-03304. Is there a similar solution?

I have connected the pins, see attached photo but did not remove the triodes. Do I have to remove the triodes? What happens if I left the triodes as is with pins connected? right now with the triodes are in the cpu, my steering wheel controls are working.

Hi,
you'd better remove it even though i also don't know there is any bad effect if you leave them .
