Hi,
I have a 2010 touran with a factory fitted rns510 version C sw2720, I have diy installed fiscon basic plus, the unit working fine most of the time.(haven't done any coding after installing fiscon unit). Everything including my Red dis and steering wheel control working ok. But some times when dialing out using Bluetooth rns510 reboots, after a min or so everything will be back to normal.(completely random). Does a firmware upgrade sort this out, if so what is the safe firmware for my unit? Also do I need to code the unit after firmware upgrade(no vcds handy).

thanks in advance for all the suggestions
