When my car (mercedes) automatically links to my paired bt phone (verizon samsung galaxy), the mercedes system clears out the phonebook and tries to download the current phonebook from the phone. I guess this is logical, however in order for this to work, I must have my phone out of my pocket, in my hand and on...waiting for the notification area to say "permission required", I must hit that notification line to bring up a screen where I have to manually approve transfering the phonebook. My phone is already paired!!! I want the phone to automatically send a phonebook to a paired device if requested by the paired device. Is there an application that will do this....or, perish the thought, a hack since I am already on Jelly Bean? This is cross posted in applications, but I suspect this is something built into Android for security...and there appears to be no way to bypass the authorization approval, even for an already paired device. Any thoughts/hints or solutions would be welcome.....No I have found no option on the mercedes to stop asking for the phonebook every time it finds a paired BT phone.
