Bluetooth Question

I have a 2011 Tacoma trd sport and I see some buttons I can't quite use. Can anyone give me some insight on how to get it working or explain some basics here? Yes I've read the manual and I do understand that this setup is aftermarket that could ave been installed by the dealer. I just can't make it work and was wondering if anyone else has this setup and has made it work.

 

It’s an aftermarket Bluetooth integration device. They’re typically either wired into the AUX, the XM, or the FM antenna.

You’ll have to do some searching to figure it out. Easiest way will be to pull the head unit (just four 10mm bolts) and see where it’s actually wired in

 

I’ve seen a switch like that though. I think the Brand was Rostra.

 

I'll pull the box. It is rostra and it looks bundled like the factory might have done it. I'll tweak with it a while before ditch it if it doesn't work. Thanks for helping hand
