hi there, does anybody know if there are any OEM audio system interface devices that work with the Toyota wired Most 50 interface?
I believe this is what I have in my 2015 RX350, i have the navigation system option.
I believe the system uses wired most 50 buss between the front -> rear amplifier.

 

Have you tried Crutchfield?

 

yes i have tried them, just tried again right now. it appears that they do not have anything that interfaces to this system.
i can try calling them to verify....?

i have heard on a different forum that the wired MOST50 communication buss system is kind of a bastard step child that no interfaces support...?
this is 2015 rx350 with navigation system. there are interfaces that work for the audio system WITHOUT nav, but the system with nav seem like they are not supported.....

hoping someone here might know of something.....
