[Q] Can't connect to car speaker phone over bluetooth

---

Hey Guys,

thats my problem:
i have a ford sony bluetooth speakers phone, but my SGS with Goatrip 4.0 can not connect the the radio via bluetooth.
i will searching for "Ford audio" in my handy display und will pairing. The Radio gives me a PIN for bonding. i type the pin in my SGS, so that the SGS say "connected to ford audio". In my Ford audio there is nothing new. After 30s it says "bonding failed".
additional to the SGS, my nokia e7 has no problems to connect to the sony radio via bluetooth.
Does anyone have a solution or know what can be the reason?

Thank you
Regards
