I'm thinking about purchasing a VCDS Hex-V2. I have a VW Transporter T6 and have tried to replace the original head unit with one from another VW Transporter of the same year. The local dealer thought he could remove the restrictive coding but unfortunately in the process we lost all phone ability! (the rest of the functions work ok since they linked it through VW to my car.
I would really like to be able to use the newer unit but without the phone function it makes it frustrating. When you press the phone button on the unit it says " Phone not available"

Will the Hex V2 be of benefit to me to fix the phone??? which was working perfectly before ????
