Neither, The truck is a 2004...I actually bought a USA-Spec model interface, it plugs into the rear of my HU where the OEM cd changer is supposed to go (I don't have a cd changer).
It offers an iPod dongle for a line-out connection which includes basic HU control of song selection as well as one additional RCA stereo input.
input selection is provided by the "mode" button on the HU.
If I select disk #6 on the HU, it selects the auxiliary RCA input, if I select Disk #5, then it selects the iPod as the input.
It also charges the iPod when it's plugged in and for up to an hour after the truck is turned off.
Bluetooth will come from my GPS.
