Phone Problem X5 E70

[bodaay]

Hi,

I have new problem that just happened after my last service check. I have HTC mobile phone which was working perfectly with my car. The problem that happened after last check( they did some sort of upgrade), I cannot pick up income call from the phone. Once I answer any incoming call from the phone it will be transferred to the car in 2 seconds. Its annoying, I used to pick up calls from the car by clicking on the answer key on steering wheel, and if its private call I pick it up from the phone.

I took my car to the dealer, they couldnt fix it and they have told me this is the normal

anyone has any idea about this problem
