Re: doesn't keep memory

DIKA, first step - check your stereo batt backup wire , you must connect that direct or continues voltage from accu. Don't switch this wire, you can check if your car in off position , this  wire must still have voltage +12v - +14v if no voltage check your fuse near batt backup wire. Why that wire must have voltage,that's because the voltage used for backup your stereo memori. OK good Try , Fixya and Don't forget to vote me, thank's

This is happeneing because the stereo does not have a battery power connections. The yellow wire is for a constant 12 volt connection. This connection is for the stereo's memory.

Is it normal during the installation of the H&B CA-8050 CD player it gets hot after working 15 minutes?

If the stereo gets to hot even when it is off, the problem can be a bad conexion and you could solve it by crossing red and yellow cables. eject the radio, check your iso connector, you can tray to cut both cables and connect them again the red to the yellow and vice versa. Refer to your manual for further information on conexions. Check also that the stereo is keeping the values you give (radio station memorys, bass - treble adjustments, etc) If the conexions are wrong, the radio doesn´t keep these values when you take the ignition key off.

I hook up a jvc kd-s16 and it will not keep the memory of the stations can you help

The yellow wire is the constant 12+V.
It has to be hooked up to a constant battery source.
If you did not install an aftermarket wiring harness consult to find the constant 12+V wire color code in your dash.
If you unhook your battery, you can splice into the cigarette lighter hot wire to keep the constant memory of stations and clock time.

Lost memory

Car stereos typically have an "ignition" and a "battery" wire. The ignition wire is connected to your ignition switch, and only supplies power to the stereo when the car is turned on. The battery wire is connected directly to the battery, and always supplies electricity to the stereo -- even when the car is off. This maintains presets, clock, and other settings in your stereo.

It sounds like your battery wire was either not hooked up, or has come loose. On your stereo, a Pioneer, this wire is yellow. Locate the yellow wire on the wiring harness on the back of your stereo. This wire should be connected directly to your battery (or another source that gets constant +12VDC).

Memory of presets

You need to Check the Wiring Harness from the Stereo. There is a Constant Power Memory Wire (Should be Yellow or Orange). This needs to be Connected to the Cigarette Lighter Power Wire for Constant Power Memory. Please Rate My Response! Thanks!

DehP6700 mp restet everytime keys is turned on.

first red is ignition or acc (turns off and on with the key) yellow is constant power (always hot keeps memory) orange is illumination (lights up radio) if vehicle doesnt have a seperate illumination wire connect it to the ignition wire. now process of elimination your ground is correct because it worked with all wires to acc your acc works because u had all them connected to it and it worked your problem is in your yellow or constant/memory i suggest u test it again take piece of wire any old thing long enough will do and run the wire directly from the battery under the hood and just run it outside the car through the window and connect it directly to the yellow wire make sure u have a good connection at the battery on the positive side if u have test light or volt meter test the wire before connecting it to the radio if it works then u know there is a problem with the wire from the vehicle (fuse wrong wire bad wire ) if it doesnt work make sure ground is connected tight and that paint is cleaned of the surface where ground connects and that the yellow wire to the radio is tight in the back of the radio.

it sounds like your hot wire and memory wire are crossed you need to place your constant +12v wire to a source which is always hot and your memory wire to your ignition when you turn on your car it all works fine

Station storage

Have you conected the stereo to 12v + before the key? If you conect the stereo after the key it will not get 12+ to the memory. It needs constant 12v+ to keep the memory...
