I feel your pain. I can't imagine how to make it any clearer than it already is.

20 pages exist in this thread only because people won't read the first three or four posts. Those first few cover it all. Your statement of "U cannot permanently ground the parking brake wire" is quite incorrect. To do the bypass, you must ground the parking brake sense wire permanently. After that, you must move the mute wire (or use another wire) to the bypass location and then ground that permanently too. Most of the twenty pages of this thread are posts from people who have damaged the pin on the mute wire when they moved it, and then refused to believe that was the problem.

I posted a circuit to cure this very problem a year or three back. I don't recall which thread it was in.

100% agreement

You move the pin of the mute wire to the new location. You ground the moved mute wire instead of connecting it to anything else. You ground the parking brake sense wire instead of connecting it to the parking brake switch. This is a really simple thing that you guys keep trying to make very complicated... It's all in the first few posts of this thread.

The third post says "I did this and grounded the newly relocated mute wire and the parking brake wire too. Semms to be working fine. Thanks AVIC411."

You're looking at the wrong connector. The connector you want plugs directly into the back of the AVIC. Go re-read the start of this thread.

Yes, leave the wire from the PAC unconnected and ground the parking brake wire from the AVIC. This has been covered at least a few times in the forums. You also do have a mute wire issue. That's why you're getting the parking brake error. You only get that error if the mute wire has not been moved to the correct location and then grounded. Did you move it to the proper slot in the connector to the AVIC? If so, then you damaged the pin in the process and it is not making contact with the AVIC. Pull it out and fix it.

It's most likely to be a problem with the cable that plugs into the iPOD. If you search this forum, you'll find that it's not an uncommon issue. The software suggestion is nonsense.

You may need a CAN bus adapter that has a switched accessory power output.

Why don't you try reading a little better/closer? It clearly says to connect the moved mute wire to ground.

I have done all this. I took my radio out 5 times to recheck all connections. It works, but when I start driving, I get the p brake lead message or w/e it is and then half my settings are gone and song labels don't show and stuff and until I come to a stop, everything is enabled. This leads me to believe that my unit requires both grounding and hacking the software. I have NO idea how to do this, so can someone PLEASE tell me how to hack my radio step by step, and not just say "data.zip" Like everyone else who has had this problem, and swore up and down that they did it all right, you have a

Did you not read the FAQs or any of the other posts? Even with the software bypass, you still have to disconnect the parking brake sense wire and then ground it.

No. And no to all the other guesses. The fifth pin on the connector in the AVIC is for the shield in the USB cable. All USB cables have this, and all USB connectors are really 5 pin. The 5th pin (or connection) is the metal hood around the connector. It's an electrical connection just like the four pins on the inside.

No wireless remote will work with the F series.
