thanks, does the T605 stop the music and you can hear the phone ringing?
Also if parrot has some wires adapter why not using that model instead?
thx
Yes, when you connect the 605, or any bluetooth kit's mute wire to the mute lead in the factory harness, it will mute the radio when you receive a call, assuming the kit sends it's mute output to ground, which appears to be the industry standard. Unfortunately, the JBL isn't fancy enough to say "Phone" like some of the Saab/Audi/VW factory units I've seen.
The only thing the Parrot includes that doesn't come with the T605 is a relay. I linked to the $9 relay from RadioShack that I used. Otherwise, the T605 was also half the price of the least expensive Parrot. If you go with one of the open box units from Tech4Less, it's about 1/3.
If I had known the Parrot's internal voice tags wouldn't work with my wife's phone, I would have saved myself $70 and put a T605 in her car. Her current phone doesn't have a voice command system, but I thought I could "push" her contacts into the Parrot to use its voice tag feature. However, it turns out her phone doesn't have bluetooth push for its address book...it'll print to a bluetooth printer, though...go figure.
It's easier to find plug-n-play harnesses for the Parrot than it is the T605. However, the plug-n-play harnesses are really designed for head units that connect directly to the speakers. In the JBL systems, the amp is actually located in the rear with the subwoofer. There aren't any speaker level outputs in the factory harness behind the JBL head unit for the plug-n-play kits to work with.
For the JBL systems, it seemed easiest to put a relay in front of the center speaker. The "normally closed" connections go to the amp. The "normally open" go to the speaker outputs from the T605. When the T605 grounds the relay, it switches the relay "input" from the JBL to the T605. The Parrots work the same way, but the relay is built into the Parrot wiring loom. There's a link in my writeup to another writeup I did for the Parrot kit in our CR-V.
The only other connections you need to make are to tap the constant and switched power, the mute line, and the ground...all in the factory harness behind the head.
The plug-n-play kits I found for the Toy/Lexus JBL systems still left it as "an excercise for the reader" to connect a system speaker to the T605/Parrot instead of using the kit's external speaker (included with T605/optional with Parrot). The only thing the PNP harnesses do is the power/mute/ground connection via locking connectors instead of a wire tap in the bundle. $50-$70 for a PNP harness or $2 for a bunch of wire taps and some fiddling with the factory wire harness.
