Hello there, 

 

I have quite a complicated issue (i think... maybe somebody would tell me its really easy fix...)

 

In my Superb 2 2012 with Skoda sound system I originally had Columbus navigation. 

 

Few days ago, it got stolen... 😞

Now I put there RNS310 (since i do not use navigation or play DVDs at all, so it does not matter). 

 

Everything was fine... until today when I fitted new bluetooth unit with number 7P6035730N because i would like to get bluetooth streaming option. 
Now problems begin. When unit is coded without media streaming, I get only error with microphone on diagnostics it say "microphone - open circuit"

Then, when i code it for media streaming, media streming works but plays just from the right side and I get error "9457427 - Left audio channel for speech/telephone B104F 13 [009] - Short to GND "

Is it coding or wiring issue? Can anybody help me what should i do to fix it please? 

Wiring - you miss a pair of cable for left channel between BT module and radio.
