Not saving audio settings?

[VRSS]

hey everyone having a problem with my head unit..
its not saving my audio settings (Bass, Treble, Sub, Midrange etc) when i turn the car off and on, i have to redo all my settings.
also whenever i turn my car on, my head unit comes on Standby, and i have to change it to CD/USB/Radio or whatever i want to listen to.
but it still saves my radio station presets.. so i dont know whats going on
thanks in advance for any help.

what type of head unit do you have?

[pr0n]

12v and accessory wire around the wrong way, just change the red and yellow ones around.
and maybe the reason it saves the radio station is because it has an internal backup battery.

And make sure the yellow wire is constant power.

R Photon, it doesnt matter which headunit cause like 99% of all headunits use the same wiring colours.

i thought all the settings were saved off constant power, but im not an expert in this area so it could have an internal battery

[pr0n]

im no expert either but i know my old sony one had an internal battery cause it would remember stations even when removed from the car. it lasted about 2 days and then it forgot them.

And make sure the yellow wire is constant power.

Yellow: + Battery wire
Red: Accessories from like cig lighter or somewhere...

I have the same problem in my VY, i have got a wiring harness from the stock wiring to my sony head unit, i have swapped over the red and the yellow wires and it is keeping its settings but now when i turn off the car the stereo keeps going buy itself.
Anyone know how to fix this?

[VRSS]

turn the head unit off when you turn your car off.. that can actually be pretty handy if you want music when the cars off you dont need to put accessories on you just turn it on

[VRSS]

well that didnt work, i swapped them over and it just does the same thing but makes a buzzing sound when it turns on like its searching for a CD..

if it makes a difference i have a Kenwood KDC-X7533U

Faulty head unit perhaps? Is there a troubleshooting guide in the manual?

[VRSS]

its not faulty its brand new and it worked perfectly fine in my old car

[Post Vintage]

I always run a new positive power wire to the battery... then find an ACC wire source from the original wiring. Make the positive power wire black also, if you want it unnoticeable in the engine back.

[Colrow]

Yea i had the same problem, all i had to do was switch the 12v wire and the acc wire around

[VRSS]

i did that but it didnt do anything..

VK_308 Sorry to say that it IS a faulty headunit, seems something happened inbetween R&R. Live with it or replace it.

[VRSS]

well im not very good with wiring is it possible i've put 2 accessories wires instead of one accessories and one 12v? or would it not even power up then?

it worked perfectly fine in my old car the same day i put it into my new one ...

[Tasmaniak]

You see, the reason I can tell you it's not the wiring is simply because it's remembering the radio presets. If it doesn't have constant power to it, it won't hold the audio settings like it's doing but it also won't hold radio stations which it's doing.

If you had your wiring mixed up, then it wouldn't even remember them. But you see, it's remembering something.

I'm sorry, but I don't have anything else to tell you. The only other thing I could think of is perhaps a setting in the CD Player itself.

Maybe StoneX might be able to provide some insight but I've never heard of wiring causing an issue like this.

[VRSS]

the thing is its not remembering the radio stations i set.. its like its just scanned the stations and remembered the ones that popped up.. lucky for me the stations i listen to are on it so i dont bother stuffing around with it

[Not_An_Abba_Fan]

That is part of the scan process, it automatically stores them once it has found them. Once you turn your key off does it lose those presets and then needs to scan again? Try running a separate fused wire from your battery to the memory(yellow) wire and see what happens.
