I've got the 50 series. Pioneer showed the 60 as being backordered. Probably because their working on the 70, not sure. Guess I could wait for the 70 instead of the 60. At this point, I'll try anything. Thanks!

I'll give it a try. I guess I can Google it to find where to download it. I'll let you know how it goes. Thanks!!

Well, looks like we ran into a dead end. We've confirmed the ground and pin are done properly. We're out of things to check. If there is something else anyone can think of, please let me know. Thanks for the help!

All good input. The unit is being looked at again Saturday 1/6. I will post what they find out. Thanks!

We'll give it a look. It's just strange that the bypass worked before the unit went back to Pioneer for service. I'll keep you posted on what we find or figure out. Thanks again!

Yeah, I understand. I'm a real good wrench but marginal on the electronic stuff. The Best Buy Tech has been great and has called some of his buddies to bounce this off. He thinks the port into the radio for the bypass went south. My understanding is that is a test/bench port the service techs use, but not sure.

"03 Expedition, Pioneer MDC, 12" Pioneer Sub with 800watt Pioneer amp. That's it.

LOL Bummer! That means my mom has been lying to me all these years. I'll head back to Best Buy and have him check it again. Thanks for the help!

Fair enough. I'll head back to see them tomorrow and have them recheck the ground for both. You don't think Pioneer would have changed something in the unit because they saw the bypass wire, do you?

The Tech assured me both are grounded, so how do I know if its updated? I'm using navi disc 2005 version 1.2. If it is, is there an additional procedure we need to perform? Thanks for your help, I really appreciate it.

The bypass that allows Nav functions while driving. The Tech confirmed that the parking brake wire was grounded and that the additional wire in the harness was grounded...just as he installed it originally. We're both scratching our heads on what may have changed since the repair.

My Avic-D1 was sent to Pioneer for service. The Tech at Best Buy pulled the unit, with the wiring harness, and sent it in to repair the screen. Unit came back yesterday and was re-installed today, but now the bypass lockout is no longer working. The lockout bypass (used procedure posted here in forum) worked great prior to sending in to Pioneer. Any ideas on what went wrong? What is the possibility the Pioneer service tech made an internal change because he/she saw the bypass wire in the harness? What can we check? Any suggestions/help is appreciated.
