Wonder if you chaps could help...?
I've got a mk5 GTi with a mk6 MFSW, rns510, and a fiscon plus installed.
When I make calls via BT and use the steering wheel controls to terminate that call I can't make any further calls unless I disconect the phone and reconnect it. It's almost like the fiscon stays in terminate mode and does not attempt to connect a new call.
On the other hand, if I make calls using the head unit, then it works like it should do and I can make multiple calls no problem. I can control the volume via the steering wheel - so long as I don't hang up using the steering wheel there is no problem...
To me it sounds like a steering wheel coding issue but the steering wheel works like it should do I'm baffled!!
Anyone had this problem before or know what it may be? Kufatec have been useless in helping out...
