a 10 year old video just helped me figure out the previous installer messed up his wires, thanks a lot for the information.

TWO YEARS.. Why did I not know about Demo mode 😂 This video is worth its weight in gold, thank you! Legend.

Although this is already a 9 year old video, it was a great help to me. Thank you!

Somebody stole my car radio and now I just sit in silence

I know that this video is over 5 Years old , i just want to say a big Thanks as this solved an issue that i was having with a Pioneer head unit that i took out of my old car and put into my Sons Ute. even though i bought a harness i still needed to swap over the red and yellow wires to stop the damn thing from resetting. Just glad that the Harness had connectors in the middle of the wires to switch.

I love when youtube videos answerd my problems.. Red on yellow and yellow on red.. Then it worked! Thanks!!!!

Bouray1, you are an absolute legend! Red-yellow and yellow-red, who woulda thunk it?!

5 minute video in 3 lines yellow = constant power red = active power dont mix them up

You deserve more likes for this. Thank you!

OMG get to the fucking point!!!!!

Waffle waffle waffle. To the point mate

I switched the yellow and red wire and it worked well for me now! Thanks :)

Great video. The fix for me was just turning off Demo Mode. Thanks man.

Thanks, now my car radio won't forget things. It worked for me after switching yellow and red cable.

wow , just had it fixed , it was a loose wire under the fuse box under the hood , left side fuse box.I spend about 30 hours looking for the problem , Lexus dealer found it in 3hours. all works perfect now.

Thank you. That really helped me 😊

Nice the yellow wire had a faulty connection thanks ! Now I can sit on the 110 with music :)

thanks, switched red and yellow wires and it works now.

My memory is fine because I wired it straight to battery. However my radio still sporadically resets when it wants to, a screen will pop up asking me to accept terms of agreement or something. I do not believe it's the stereo because the unit before this one did the same thing every once in awhile. The other unit I tried before my current Jensen would turn off completely and I would have to disconnect battery and reconnect before unit would come on. Like I said my memory is fine on current unit but is does do resets sporadically when I start vehicle. Could my problem possibly be a bad/ dirty ignition switch?it definitely seems like problem has worsened since I added a remote start.

Thank you for your help. I now have a full working radio

Hey man thanks.My radio was connected right but I switched yellow and red and now it works and doesn't reset every single time.

Thanks you just saved my head unit getting chucked out my car window

Thank you. Just got my radio to save all the settings! cheers

Saved me a lot of time - Thanks!

i love u! i solved my problem. yellow end red wire were swithed. TOYOTA AYGO

thanks man I had the yellow wire hooked up to switch power instead of constant yay thank you so much bro

Thanks you very much!! you helped me a lot with this video!!!

Thanks bud. Don’t know why people can’t follow simple color to color wiring. 👍🏻🤙🏻

you absolute legend, god bless you

make sure your black wire on your radio is hooked to ground, if you have 12 volts on the yellow and red wire and you know for sure the radio is grounded, then it should come on.

I have a FIAT STILO and not long ago I bought a Radio MP5 7018B , but I discovered that the Radio heats up a lot, will the wires be wrongly connected, if so, how should they be connected?

my radio drains my battery. is it okay to disconnect the constant power (yellow) and solve the draining problem

Thanks, this helped. Not sure why so much dislikes.

I swear that my unit was broken, or I did some wrong wiring, but it was simply in demo mode…. Thank you so much!

Was the same in my case in my Peugeot 206, just matter of changing the wires. I was worried i would have to cut wires and mess around with the ignition and the battery, like some suggest in some forums. Perhaps that was how you had to do on older models.

Fixed my issue on the new to me 1997 Wrangler.

Great vid! My presets last about 2-3 weeks, then, wen I go to start car, gone. It happened to me wile the car was being driven for the first time, a few days ago. Wat could it b???!😩 Thx👍🏼

Kenwood Excelon KDC-X597 connect all wires color to color, channels will not save. Switch red with yellow and channels will save. 1993 S10 using new Autozone harness.

thanks. that was my issue. it also solved the issue that the radio was always shuting dows on loud music. hi5!

Thanks for making this video My demo mode was on and couldn’t figure out what the hell was goin on lmmfao

Thanks! You helped me a lot with this Video!

I have a 1989 GMC pick up same issue that you just explain can I get my constant from cigirrette lighter?

Legend thankyou you just saved me £100s

I replaced a stock radio in my 2001 sunfire that intermittently lost the clock settings , noticing it at ignition start. I replaced it with a new radio which now has the same problem. It loses settings only sometimes. Never during a ride, always during ignition off. What do I need to look for? I made sure the ground was screwed down tight to the frame. I double checked red and yellow wires. I even replaced the battery ground wire that had some corrosion. Help!

so my radio will not turn on at all unless both yellow and both red are wired all 4 together.. any idea why? also my radio remembers sound settings like bass and even remembers the background i chose but makes me go through the initial setup like demo mode everytime and doesnt remember time or station presets HELPPPP

thank you so much, let me go try it out i hope it works!

Thank you very much on this. Helped me! :)

My factory yellow is bad so i have to connect it together they told me its just a fuse but idk wich one it is

I have swapped two, and the radio saves all the settings, but I is on even after I pull my key out. Is this something I would have to live with?

You’re a legend

Thank , will have a look and see if i can fix this annoying issue .

Thank you brother great video

im having problem draining my battery because of my head unit, i tap the yellow wire to red wire so my head unit will not have constant power and i leave the yellow wire disconnected to any wire, it works but ky problem now everytime i switch off the ignition my settings are all gone. is it safe to swap the red and yellow wire? pls help me

I even checked the voltage out of them confirming switched red power and constant 12 volt out yellow yet I Still loose settings memory most of the time but not always. Replaced the player with same model, same problem. Nothing worse than an intermittent problem. No issue with previous radio.

Thanks.

My car radio doesn't turn on unless I touch the red and the yellow together, and than it didn't turn off. So I had to run a wire from the fuse box to make the radio turn off when the car was off. But it still doesn't turn on unless the yellow is touching, (even when the car is on). I need to know why it doesn't turn on with the yellow. Its an 01 Malibu. Any help would be greatly appreciated.

Tak!

I have an issues with Skoda Fabia 2007, the have bridged the Red and Yellow wire at the main connection box, which is the only way to get the radio to switch on. However this is stopping the central locking from working. I have switched the yellow and Red wire around which doesn't make any difference. I have checked all fuses which are all working fine. once I disconnect power from the radio my central locking works. what could be the problem?

I dont have a yellow wire, what's goin on? Previus radio worked fine new oneforgets its settings

I’ll go try it again but I recall trying to switch the wires and nothing and the radio was working fine I switched the radio out my car to my truck and the on e in my truck to the car cause I sold the car and I had the same problems in my truck with other radio and it worked fine in the car as well so ima check my ground if not idk what else to do

I bought a kenworth that had a fairly new stereo, but it was acting funny. I tried to turn it up, but it had dead spot on the valume. I went to my settings, the same thing finally when I set my settings the way I wanted them I shut truck off but when I turned it on everything had clear so I checked the wiring harness found everything ok but the red and yellow were hook together to the red wire to the truck,can that be causing the stereo to act up like that?

Great video, saved me loads of time. Thank you.

I did it red n yellow n still no save the station radio n i have to turnd the radio manully evetime i use my car n set the radionstation? Is soundstream double din.

In my yellow cable always is 12 V but when I switched off always lost the memory, but I measured 12V. Why is the reason?

My OEM harness is labeled and the yellow says 12 volt memory. The red one says 12 volt accessories. I have it hooked up and the radio will not boot up.

demo mode keeps coming back on for me everytime I turn the car on

would adding red and yellow wire together cause the non saving problem because my AU FAIRMONT didnt have the proper wiring so we had to do it another way?

Where is your remote turn on wire?

What if your vehicle has a killswitch installed? I have a 2003 GMC Sierra I bought last summer that had an aftermarket radio in it that would save my settings so I thought I'd swap it out with another aftermarket radio and I still had the same problem. The new radio would not save the settings.

I attached my red and yellow together. Is that why my settings are not saving?
