I own a 2005 prius package b -"no nav and no integrated bluetooth" I have done about five fun-filled hours of web searching and found tons of information about the prius, except installing aftermarket bluetooth kits. Hope the commuinty can help me out. I am installing a motorola hf850 car kit. The directions state: 1) Connect the motorola fuse kit's green ignition sense wire (3 amp fuse) to an ignition-switched location on the fuse box. Does anyone else know where the ignition-switched location on the fuse box is? 2) Connect the motorola power cable's orange entertainment mute wire to the vehicle's entertainment system. I believe that my stereo system has an entertainment jack or fuse, being that bluetooth is an option in package d, but where is it? Will it require a relay? 3) Connect the motorola fuse kit's red positive lead (4 amp fuse) to a point in the vehicles fuse box THAT is fused a 4 to 5 amps. Where is the fuse box and is that the same place where the ignition switch is? 4) Connect the motorola fuse kit's black ground wire to the chassis. I assume as long as the black wire is touching the metal frame, I'm grounded. I can do wiring and splicing without a problem, but I'm lost when it comes to prius electronics. I will post progress pictures if all goes well and we can post it in the diy audio section.
