    Hi. Thanks. Yes its sorted. I was installing in on my (17 year old tomorrow) son's 1999 Corsa that we've bought him for his birthday and the original radio had been removed when we bought it. I swapped the yellow and red bullet connecters round in the wiring harness that was with the radio and hey presto. Incidentally, I have just finished checking eerything I think this CD/radio is superb. Thanks again.

Most current car head units requires two (2) kinds of B + supply; the yellow should be connected to an always on/constant B+12 such as the positive terminal of the battery. This is responsible for the memory and setting/configurations not to be erased when powered off. The red wire is connected to a switchable B+12 such as the ACC terminal of the IGN switch making the radio work only when the key is turned to ACC. Of course,the black is ocnnected to the chassis/ground.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Jbl radio A56840 loses station presets and no volume

Toyota vehicles have a fuse in the kick for the amp and sometimes there is located under the hood ... This is the switch turn on for the amp ... And 1 of the fuses is most likely the memory or constant power. B sure to check all fuses ... I do not have AllData pulled up . If the fuses are all good the amp or radio may be bad ... Or both ... Be sure to check all the fuses ... Many times I get clients that say allthe fuses are good and it is still the first thing I check ..Usually is a fuse ..Good Luck

How to enter a Ford Radio Code

To enter the security code and get your radio up and running again follow these instructions;

Turn the radio on and the display will show ' CODE - - - -

Press preset button [ 1 ] repeatedly to get the first digit on the display

Press preset button [ 2 ] repeatedly for the second digit

Press preset button [ 3 ] repeatedly for the third digit

Press preset button [ 4 ] repeatedly for the fourth digit

To enter the code press the [ 5 ] key to accept.

The set should now operate.

If you have lost the code to your radio

Remove the radio from the dash and find the serial number of the radio which is on a label on the case.

For European Ford Radios you can get your code here for £3.50 using the serial number of the radio.

I have used this site numerous times and can confidently recommend the service as fast and accurate. This site is for European Fords only.

Ford dealerships charge over £20 for this so there is a considerable saving in using this service.

For USA Fords you will need to contact your local Ford Dealership with the VIN number of your car. Expect to pay $30 - $50.

Hope this Tip helps. Please do leave a vote for it. Many Thanks.

When i preset my radio stations 1-6 while the power is still to the system memory of stations will stay but when the car stereo power is turn off for any amount of time and sterio is turn back on all...

Make sure the yellow wire is connected to a source that still has voltage when the key is turned off. The yellow wire controls the memory of the deck.

Does not stay set.

your deck has two power sources a main for when your car is turned on so the radio kicks on and a remote which is always on keeping stations and clock powered passively so whoever installed it did it improperly or do to road wear and tear it was jossled lose and can simply tightened after pulling the deck out

When i turn the ignition off i lose all radio presets. What wire needs to be live to keep the presets??

The Yellow wire is 12volt battery constant on after- market receiver heads.

Jvc car cd/radio

The radio was improperly installed; there are two 12V leads, one services the radio when on, the other, only the circuitry for the clock and presets.
Eventually, this shouldn't be needed if the manufacturers ever think about using a little bit of flash memory for the presets and a coin cell for the clock.

You didn't give any model number so researching the manual is impossible.
If you can find the model number, look for a user's (or installation) guide on line to find the wiring info.

Same as all Pioneers. With the car on or in ACC position press and hold SOURCE until the radio turns off. Press and hold FUNC to enter the menu. Use the four arrow keys to navigate and make changes.

Stored settings and auto eject

Hi. SOunds like another case of power problems. Your deck has 2 power wires. One is yellow th eother is red. One is constant 12 volt battery power, the other is a switched 12 volt power, only has power with the ignition key on or on accesory. Get yourself a test light. I almost bet you do not have the constant 12 volt power to the deck, therefore your deck cannot hold its presets...
