I guess, the best thing to do is, while pairing one
of your phones, to totally switch off the other one
, i.e the one you are currently not
Thereby, you make sure, thereīs no second bluetooth signal available for the HFT to confuse it.
Each time you failed, you should remove your key from the ignition and reinsert it to return to a default situation for the HFT.
Of course, if it still doesnīt work, your dealerīs help seems inevitable.
Oh,... let me add this:
I didnīt get my C905 paired, neither, until I found out, I had to confirm the start of the pairing procedure with a "double click" on the phone.
Maybe this will do the trick for you, too?
Just wondering, isnīt this whatīs called "discovery mode"?
