Mister Murse Posted July 20, 2011 Report Share Posted July 20, 2011 So, I installed my Z120BT and bypassed it using the method seen all over this forum as well as the videos shown by Sound Man Car Audio. As was/is the case with many others, for the first few days it worked flawlessly...and I loved it! But now I intermittently get the "Caution: The system detected improper wiring...blah blah blah" message. So here are my questions... 1. Anyone experience their bypass working intermittently? (It's random too; I haven't detected any pattern to it or any certain car startup procedure...sometimes it works, sometimes it doesn't) 2. For those who previously posted who were in the same situation, I see the guidance from other members is to check and recheck your wiring...but can you chime back in here again and say if you were actually able to solve your problem and what it is you found worked for you? I searched a lot on this forum and mostly see people ask for help, but not always re-post saying the help worked and this is what they did, etc. Thanks everyone, much appreciated!

Mister Murse Posted July 24, 2011 Author Report Share Posted July 24, 2011 BUMP. Anyone with a similar experience? Gonna rip apart my dash tomorrow, any advice/hints/tips greatly appreciated. Quote Link to post Share on other sites
scgti Posted August 4, 2011 Report Share Posted August 4, 2011 I did this over the weekend. It definitely sounds like you've got a loose wiring connection somewhere. To make sure all my connections were solid, I used a butt connector to connect the ground from the harness connected to my headunit to the ground from the harness connected to the car's wiring harness. I then used two scotch locks, one for the parking brake wire and one for the mute wire, to splice into the ground wire. Make sure all of these connections are solid. The only other thing to look at is the pin where you moved the mute wire over. Make sure it's securely inserted into the harness with room for movement if you wiggle it.

dallas5cowns Posted August 9, 2011 Report Share Posted August 9, 2011 Had the same issue. Make sure that plug that has the parking brake wire is plugged in securely. I took my unit out and pressed all the connections together, heard a little "click" when I pressed this block and everything has been good since then. Quote Link to post Share on other sites
Mister Murse Posted August 20, 2011 Author Report Share Posted August 20, 2011 Thanks for all the input...a few days ago I pulled out the HU to install a backup cam and while I had it out I redid some of the wiring. Put everything back in and it works again...for now...so we'll see if this one lasts. Thanks again!. Quote Link to post Share on other sites
Mister Murse Posted August 28, 2011 Author Report Share Posted August 28, 2011 So the hack worked for about a 1 week this time with no glitch but again yesterday I've been getting the "message." I guess I'll be looking forward to pulling out the HU again...sigh...any new ideas anyone? How exactly do you have yours grounded? I have my 1. moved yellow mute wire, 2. Pioneer side ground wire, and 3. parking brake wire soldered to the 1. ground wire of the aftermarket harness. Thanks again everyone! Quote Link to post Share on other sites
Blkt Posted December 29, 2011 Report Share Posted December 29, 2011 My mute wire came in the bypass location so I moved it one pin over. Bypass didn't work. The screen retention harness connected to the mute wire so I had to moved it back to the original location. Not sure how to by pass and I have read a number of threads from others. I tried a relay to ground the parking break, remote turn on & chaise ground together. Still didn't work. The video goes off when I go above 10mph but turns back on (still in drive) at a stop lights. Any suggestions would be appreciated. I think it might be the VSS... Quote Link to post Share on other sites
JEA Posted February 15, 2012 Report Share Posted February 15, 2012 I know this thread is a bit old, but I am having the same "message" issue, but I have found mine does is when the HU is cold. After I turn on the heater for a bit, and restart my truck it works just fine. Hope that helps. Quote Link to post Share on other sites
