Pioneer Bluetooth I cannot connect my phone to the bluetooth without some pin code. The phone says " enter pioneer hdd navigation pin code " but neither the bluetooth component or the head unit manuals say anything about a pin code.

check the bluetooth version on both units. which is newer? the phone or the radio? they may just be incompatible.

you can try disconnection the power to the radio for 5 minutes (all the power not just the main power) then reconnect it and see it it reset.

Try 0000 or 1234 - most are initially set to one of these.

As far as I know the default passkey for the Pioneer AVIC devices is 1111 (four ones). By the way, it seems that there two ways to pair this device. If, after display the settings menu and selecting 'Bluetooth settings', you choose 'Register from mobile phone', after you phone is paired, all subsequent connection requests will be started from your phone. Otherwise, if you choose 'Select specific devices' instead, all connections will be started from the navigation system.

Hope you are able to get your navigation system fully functioning soon.

Anyway, please, let me know if you need further informations.

Best regards,
Carlos

You have to enter the security code into your phone once the phone receives the connect to signal from the radio, the default code is 1111

have you upgraded the firmware on this unit ?
his firmware update (version 2.0) contains important performance improvements relating to, among other things, boot-up time, Bluetooth connectivity (including certain Blackberry models), iPod Touch (v2.0) compatibility, touch screen response, display brightness, and SD and USB media playback.

The Code to activate it is 83423

on pioneer head units u can only use apple ipod and nano and up....if its a usb cord then it should work but if it is only the hook up off the cd player nano and up and only apple ipods

Can you be more specific like what are you pairing your D3 with, and when you turn down the volume? The volume of the D3 or the pairing device? More info would be helpful.
