The PAC-SWI modules I beleive are known to not be all that reliable.

 

are there any newer versions that would work better? and I definitely won't try anything myself, but I still don't understand why it's just the down button lol

 

Yes: Metra Axxess ASWC

 

any way to tell which module I have now? just so I actually somewhat know what to talk about when I give them a call.

 

Ask the shop who put it in or look at your receipt.
Besides that, take out your deck and look.

i just remove one from my altima, i had full list of bug with pac

i just install Metra ASWC and update it to the last firmware and its a gift from the sky hahahahah , work perfectly and i can map source button to voice control
