Thanks for the info but not sucess, at least for me. Maybe because I have an euro F900, maybe due to my HTC Rom, maybe due to the weather, the moon phase ...
My problem is that the HTC do not automatically syncro as you state and when you want to send the contacts the AVIC is not selectable on the HTC the to select it (possible becasuse on this moment the AVIC has no visibility set).
Today I have tried another workaround that I have to investigate deeper. The procedure was:
1) once that the Navi and the phone are already connected and without disconnect them, select a single contact on the phone and choose to transfer via Bluetooth. Obviously up to now, nothing happens as the "Pionner Navi" does not appear.
2) In order to appear selectable without disconnecting both units I selected
Phone settings > Connection > New Connection > Pair from phone.
3) Just then, the Navi appear in the HTC being possible to select it and the HTC send the contact.
4) After complete the sending I aborted the pair from the phone returning to phone setting menu and select transfer contact saying OK to everything.
With this method I finally send a single contact.
I have tried to send several contacts one by one before point 4) and when you get bored, oerform step 4) and ALL of them appear on the Navi (plus the one sent before tha has been maintained)
Later I tried selecting up to 6 on a single shoot and works OK even having sending more than one package after to select transfer contacs again.
After each step 4) I had more contacts transmited and finally was too late and I quit having achieved to sent around 40.
Today I did not try with this method send the whole agenda, but I think that I have tried before obtaining always an error msg trying to send the complete set of contacts (around 200)
