Weird RNS 510 version C / Skoda Bluetooth Problem
flyboy1976:
Guys this one beats me totally. my RNS 510 version B works fine with my version B skoda bluetooth. When i installed a Version C RNS into my car it kept on throwing a fault code under controller 77 (Telephone) which said 'Open Circuit'on the microphone. Plug the version B back in and it works fine, yet if you use the version C the Mic doesnt work and you get a fault code as mentioned above! so when you make a call no one can hear you.....this one has stumped me. I have voice activation enabled on s/w 2720 that im running on my version B unit and i have treid x2 version C's (one with 2680 the other with 2720) and they both have the same issue but the version B works a treat no fault codes and Mic works as you would assume it to. Do the Version C's have a different pin config on the telephone (green) socket compaired to the older units? it acts as if i dont have the mic connected up when i plug in any Version C unit into my car. I have made sure it is coded correctly as per the version B but im at a total loss on this one! please help guys. the voice command works fine on both units as well, its just when making or receiving calls you can hear the other person but they cant hear you!!!!! HELP!!!!

I don't know what to suggest other than teaching you how to suck eggs and say are you resetting the c versions after coding? Sorry if you already have tried this?
I know how frustrating it is trying to fathom something out when it seems so easy, but there is possibly something very simple you have just over looked but without seeing the car its hard to say what it might be, but would certainly put it down to the units.

yeah did that as i changed the displays from highline to sportsline. it just throws a code 'open circuit' microphone and the mic doesnt work when making or receiving calls, but only on version c units! is there something in the adaption of controller 37/56that im missing? thanks darren in advance. maybe vrscarl has an idea or cameluk?

The other suck eggs question is have you got it wired for Voice?
Perhaps worth posting up the coding of 56 & 77.
flyboy1976:
was just emailing you stu. coding for 77 telephone is set to 0000322 and long coding on controller 37/56 is set to: 04 00 04 02 04 00 00 10 00. the unit is wired from mic into pins 1 and 7 (in) then from 4 and 9 (out) into BT module pins 11 and 12, works no probs on version B but plug a version C in and it throws an open circuit fault code for the microphone under controller 77 and basically the mic only works for voice activation but not for the phone! help!!!! not that its relevant but i am using the latest gateway. also it makes no difference if i enable or disable microphone diagnostics either, still same problem persists. the only thing i havent got activated or checked is this: http://www.my-gti.com/wp-content/uploads/vw_rns_510_vcds_coding_4.jpg
The problem to me seems like the BT module is picking up a fault between pins 11 and 12 on the BT and not talking to pins 4 and 9 on the sat nav....its as if i havent plugged them in, i checked all connections and they are good, im sure its something with the adaption that you need to activate to tell the sat nav that you are using pins 4 and 9 for microphone, this is my theory.....anyone?
what are shortpress steering wheel buttons exactly? is this mk6 related as i have the later type MFSW controls (i currently have this option unchecked)
i have MFSW / HIGHLINE / and Skoda BT version B for red dot DIS
