Need help with Bluetooth in ordering Aux replacement

[Nick Ford]

I recently had my speakers changed out a friend of mine, help me with it. For some reason the Bluetooth does not exist anymore. I’m not sure if there’s a sensor that might be disconnected. Also, only two of the six speakers light up ran all the wires.
In addition, I want to order a replacement USB ox because mine is rusted out but not sure which one to get. I have a 2018 212 s limited Yamaha .

many help would be fantastic

thank you

Bluetooth is typically built into the head unit, so either it got turned off or just went out. As far as speakers lighting up I assume you are talking about LED lights built into the speakers. If some light up and others don't it has to be a wiring issue... Are they piggy backed or do all the wires run to power somewhere? If they jump from speaker to speaker they may not be getting enough juice.
