If I remember correctly, that yellow harness connector goes directly into the back of the HU.Well I got my head unit today, finally. Once it finally actually shipped it got here QUICK. Literally shipped from China last night and had it this afternoon here in Dallas.
I didn't get home from work until after it was already dark so I couldn't mess with the unit too much, but I did set it in place and did a really basic hook up on it. Some of the harnesses I'm not really sure what they're for. Unfortunately, one of my harnesses has a wire that came un-crimped out of the connector:
I'm wondering if I really need this harness anyway. Is the one labeled 3G USB simply an input for a 3G modem? I definitely will not be using one of those. Likewise, is the one labeled DVD USB an input for a DVD player? If so, I don't care about that either and thankfully this damaged harness is not an issue for me.
For 1) Not silly at all. The glow light plays a large aesthetic role and helps tie the different components of the car together rather than making it look like a chop shop of aftermarket parts. It's my understanding that the glow light color can be changed within the HUs settings. Unfortunately I couldn't tell you exactly where because I had told the seller before hand that I wanted the lights white so they were already white when I received it.A couple of observations:
1) The buttons on my unit are all red! I guess it's silly to be upset about this because the listing clearly states that the buttons light up red, but the fact that all you guys got white buttons gave me false hope I guess. I really hate red buttons and interior lights in cars so this is a real bummer. I don't suppose that the color is changeable in settings or something?
2) I hooked up the GPS antenna but it does not seem to be working. Does it need to be turned on somehow in settings? Is the GPS signal for some reason dependent on a data connection? I did not have wifi connected. Is there another trick other than just making sure the GPS antenna is hooked up? When I open the GPS app it seems to think I'm in San Antonio for some reason even though I'm in Dallas, although it doesn't seem to actually be locating me because it shows "looking for GPS signal". Maybe it just defaults to San Antonio as some sort of demo location for all I know. Regardless, is there something extra I should be doing to properly enable GPS?
Oh I did find where everything plugs in - I just wanted to confirm that this damaged harness is irrelevant to me because I will not be using a 3G modem dongle or care to play an external DVD USB player or anything like that (assuming that is indeed what those USB plugs are for).If I remember correctly, that yellow harness connector goes directly into the back of the HU.
Each male harness connector has a small notch on the side so it can only go into one of the female connectors on the back of the HU. Gently try plugging into each of the slots on the back of the HU until you find the one that fits. You may not need or use the modem USB or the DVD USB but you'll likely want that canbus cable plugged in.
I couldn't find it at all in the settings last night. All I could find was general screen brightness and whatnot. I'm suspecting that I may be SOL and they aren't able to be changed. My fault for just assuming mine would come white despite the ad listing red as y'alls came white.For 1) Not silly at all.

No I was outside in the driveway and I just had the GPS antenna kind of loosely sitting amongst the wiring. I did find the two apps that showed GPS signal strength but it was gibberish to me. Thanks for the heads up on placing the antennas in that center dash grille. I'll try again tonight.For 2) GPS does not require any data connection to detect your position. It could be that you positioned the GPS antenna in such a position that it doesn't get a strong signal. Where did you place the antenna? There's two apps on the HU that will display the GPS signal strength in real time. I ended up placing the GPS antenna in the same location as the stock GPS antenna per @guy989 suggestion here. Also are you inside a garage? My signal strength drops significantly inside my garage where I did my original install.
Mine is a 2014 manual transmission "Sport" trim. It does not have factory Bose, factory tech package, factory backup cam or anything like that.I did not have this connector. What year and trim is your car? Do you have the factory tech package?
Thank you, that really clears up a lot for me. I was getting hung up on the labels thinking they were specific to a DVD player or 3G modem vs. just being standard USB connectors that could connect to just about anything.Yeah I'd still request a replacement, and while I was waiting, try to fix the existing connector.
@MadStyle is correct, even with that adapter, it still doesn't work. My only guess is that mazda swapped some pins on their harness in comparison to others which is why that adapter doesn't work. It fits, but doesn't operate as a full-fledged USB connection. I have a feeling if someone was determined, they could figure out a way to make it work, but it was never worth the hassle to me.
The USB plugs labeled 3G and DVD are just standard USB 2.0 connectors. They provide .5 amps of power, and allow you to connect devices like thumb drives, USB-powered 3G modems, etc. I just used a USB to USB extension cable to extend the length. Pretty sure the unit comes with one. You can even connect a usb hub to get extra USB ports out of a single connection, but be mindful of the .5 amps... don't expect it to power devices that need a lot of power. Thumb drives etc work fine tho.
Dang I see you already pointed out the reverse trigger wire over a year ago here http://forum.mazda6club.com/electrical/314481-rear-view-camera-aftermarket-hu-2.html#post4538610@james92se, i went through all that already. See here -
If you follow the steps in that post & the other thread I linked, you'll be good to go. I think you are having the same issue I had.
