BT connection to Becker PNA Traffic Assist Z 200

[Guest Stefan968]

Hello,

I have a Becker PNA Traffic Assist Z 200 that offers a BT hands free function.

With my Nokia 6300 and 5500 all works find but not with the S710.

The connection is established and the telephone book unsuccessful transmit to the Z200.

But if I call somewhere or get a call the caller can't here me. On the Z200 the quality is also really bad like crosstalk.

Is there any possibility to get the issue under control?

I tested it with the original HTC ROM, Dr. Martin Gonzo 6.1 and now I run the NEO ROM for Vox v0.9.

With all ROMs the same problem.
