BESIGN BK01 Bluetooth Car Kit, Wireless Aux Receiver for Handsfree Calls and Music Streaming with Ground Loop Noise Filter for Car with Aux Port

I've had this thing for about 6 years: https://www.amazon.com/dp/B0DZBC22KG?th=1 I don't know if it's the best-sounding receiver on the market, but its good enough that I've never thought about replacing it. It's dead simple and plugs into the aux port for sound. There's a good spot for the receiver on the right side of the gear shifter, which is where I've put mine.

Turns out it was an old Bluetooth device that was shorting out the whole system and draining my battery as well. I think it nuked a few batteries in my old car. Replaced it with an updated version: https://amzn.to/4vz2pnl Now I have yet to have another short. Now to figure out why the center 12v plug keeps spitting out my 12v charger.
