I didn't really think it would make a difference but moved the ground to here and same issue persists. I verified I have continuity from the screw to chassis ground.

Thanks for hanging in there with me folks.

All wires are connected from HU. The only two wires from interface no connected are the lt green wire and pink(says "phone mute"). Here's one more pic trying to show all wires connected.

What did you connect to the USB ? Not sure why grounding the Lt. Green wire isn't working for you, I know it's work for many others, unless Kenwood changed something, but I don't think they did. Were you able to get your phone connected yet ? Maybe you'll need to try connecting the Lt. Green wire to the Lt. Green wire from the interface and forget about the bypass. Perhaps someone who has the same head unit as you will chime in here, and let us know if the bypass worked on theirs.

The Pink wire is the VSS (Vehicle Speed Sensor) connection which is used by navigation systems, which yours isn't.

Apparently, I cannot connect my phone to BT because the HU thinks the car isn't parked. I connected my phone via USB in an attempt to link via Android Auto and got "stop your car....." message.

Thanks for confirmation about the pink wire.

I suppose I can hook the lt green wire to the interface. But that would mean I cannot bypass the parking brake(deal breaker for me). I'll see what some others might say. I might need to start a separate thread to address this.

Yeah, connecting it the the Lt. Green wires will mean you'll have to have the parking brake engaged to access the menu. On my Pioneer grounding the Lt. Green wire works fine, I have access to all the menus. On mine I connected it to the ground wire between the interface and head unit and not the head unit itself, not that I think it'll make any difference with yours.

Ok, just for the heck of it, I connected the lt green to the lt green on the interface. "Select device" is still grayed out. Ironically, the YouTube video you posted(in the "slim pickings" thread) about how to bypass the brake in on a Kenwood.

I suppose my next step is to contact Kenwood.

Well that's strange it's grayed out on the video. Did you have the parking brake applied ? I can tell you for liability reasons Kenwood won't help you with the bypass, but perhaps they can give you a reason why it's grayed out with the parking brake applied. Just out of curiosity, are you trying all this with the car running or just in accessory mode ?

Parking brake is applied. Car is not running but in accessory mode. We can be stumped together.

Have you tried anything with the car running and the brake applied ?

It's up to you, I know on my Pioneer the backup camera won't work unless the car is running, maybe there's something similar with the Kenwood.

Cut the brown mute wire and connect the loop back as it was. No need to hook up the mute wire on the radio harness, your swc will take care of that. Should solve your problem.

I scanned for devices from my phone while having the bluetooth menu open. "Select device" is still greyed out.

PAC instructions say cut brown loop and connect the HU and this is what I have done. I'll try connecting the brown loop back to itself. Thanks.

I thought you were onto something because in the Kenwood manual it even says "brown" "not used" for the DMX706S. But the PAC instructions say "If the aftermarket radio has mute input, cut this loop and connect the outer brown wire to the mute input." Hmm, I wonder if I had the "outer brown" wire connected or the inner. There might be something to that although it seems unlikely that the mute wire would have something to do with connecting BT or the apparent parking brake.

I just re-connected the brown loop on the PAC interface. However "select device" is still greyed out.

Could try a transition of the parking break: ON-OFF-ON

I've read that some head units need to see this transition.

The mute wire is for OnStar. Basically sends a signal to mute the head unit when OnStar is being used. I'm not sure how that would effect your issue but I guess anything is worth a shot at this point. Also a couple of other things to check.

1- Try the parking brake procedure NBVette mentions
2- Make sure your crimp connection to the red o-ring terminal is good and the actual bare wire has a good connection to the o-ring and not the plastic (parking brake wire)
3- Your owners manual mentions that "it is necessary to register the cell-phone in this unit before using the Bluetooth function". It gives the steps to register it into the head unit before moving on to the steps "select device" that you mention. It seems a little confusing to me and redundant, but at this point I would try to strictly follow the steps the manual lays out.

Here is the manual, page 52 mentions registering and bluetooth setup,

That should be a 1 time thing, if it worked. Basically the first time you connect the head unit.
