I just purchased this radio and had it professionally installed. When I shut it down/shut down car, I lose most of the programming. Why?

You have two power wires on the radio. The red one is for switched ignition. The yellow is for constant battery power. The sole function of the ignition wire is to be able to turn the radio on & off with the key. The constant wire is the one that actually powers the radio when it's on & keeps the memory when the car is off. If the radio doesn't have constant power on this wire, it will lose its memory every time. Very old cars (early 80's & before) do not have a constant wire in the factory harness. In that case a new connection must be made. That connection needs a 10 amp fuse for fire protection. On newer cars, the most common cause of this issue is when the constant & ignition wires are hooked up backwards (eg. Constant to ignition;ignition to constant) Either way, the shop is most likely at fault & should fix it at no charge. Hope this helps. Edit: I just noticed you had asked earlier about compatibility with the Mercedes SLK. If that's the car the radio went in, then your power wires are indeed reversed. The harness is color coded incorrectly for that car. The harness plug fits many European cars but in the factory Mercedes harness, those 2 wires are reversed. It needs to be wired to the radio - red to yellow / yellow to red.

I suspect your professional installer did not provide power to the constant hot (usually yellow wire) this wire must have a continuous 12 volts(not switched) look at your manual, take it back!

Whomever you had install it did so incorrectly. There is a wire that has power all the time, this power keeps your clocks and other things in the vehicle powered including the radio. If it is hooked up to a wire that only has power when the key is on you will loose programming everytime it is turned off. You need to take it back to your installer and have it fixed, pretty easy fix.

I would ask whoever installed it. I asked my son who installed it for my daughter. He said ask him if he has a wiring harness. The person who installed yours should know what that is.

That should not be happening brother. Please contact the professional installer to have them take a look at what may be causing this and if it turns out to be the deck itself Amazon is great about replacing anything they have sold that turns out to be defective in any way. Hope everything works out.

Yes it will happen if you have a power shut down , remember to remove the face first. It also help to note your statiin somewhere..

You may have a wire crossed. My works just as the oem did. I took a picture of the wires before removing the old one and put the wires back on the exact same way. When mine hits temperature setting (either heat or AC) it shuts off automatic.

I had the same issue. I believe it is a function that is not included in the head unit. I just had to get used to it.

If its ok for a week or so I would suspect an issue with one of the 2 power wires or the ground connection....something that is causing loss of power to the head unit will reset it...even a loose battery cable can do it.

If you have anti-theft deterrent system, it may be necessary to disconnect the fuse for the radio to program more than one remote to your vehicle. My 04 had anti-theft and 1,2 position.

Go to menu and select another radio call number that is a "dead spot" on your radio. If you have an auxiliary output, plug your radio into that and avoid the interference

Yes, the battery appears to be working now and I am seeing the goodbye image when I shut off my ignition. It looks like the same unit I sent back. How did you fix it?

I looked in the manual for an official answer to your question, but didn't find one. Sorry. I can tell you that it did shut down on me. It was an oil sensor issue. Since then, I made sure that I changed the oil frequently, and it has performed well.

When I installed this radio it didn't work at first, I later found out that I just needed to replace a fuse! Check your owners manual as to where the "Radio Fuse" is in your car. Then check it in your vehicle, if the wire inside the fuse is a solid line then its not the fuse. However if it is broken in the middle than you just need to replace the fuse and it should work perfectly. My car calls for a "4 amp fuse" but I put in a "5 amp fuse" so it wouldn't blow because of little power fluctuations in my car. Hope I helped!

I'm a mechanic and yes it will drain the battery if you leave it plugged in while the car is off, my suggestion is to hard wire it into the car with an "add a fuse" , it's simple and cheap and will turn on and off with the car without draining the battery (look up a video on YouTube "how to hardwire in a radar detector")

It is to replace a stock radio but it loses memory whenever you try to start the vehicle if you are listening to the SD card you have to reprogram the stations and clock

I believe that is untrue. That owner likely misfired his unit. There should be a primary wire to power that is turned on by the ignition key. I think there is a secondary line that goes direct to battery so that the presets do not get lost.

I have had this problem. It has locked up and been unresponsive (although it continued to play music) and it wouldn't turn off when I turned my car off. I also have an issue that I will start my car and no sound will come out of the unit. It will show song information, show the time counting for the song, but no sound. The graphic equalizer is also flat indicating that it isn't processing any sound. I have since replaced the deck and have already started to have issues with no sound. My dealer is trying to work with their Kenwood rep., but so far there has been no news of what the issue is. I have had this problem.

if you hook it straight to the battery the radio will stay on when you turn the car off and you'll have to turn the radio off each time. if you use the red wire on the fuse box it will shut off each time you turn the car off. the volume button on your radio will adjust determ and your Bluetooth. I hope this helps you.

No, My plug stays hot when vehicle is off so the radio stays on. I have to turn it off manually.

Radio settings are usually lost when battery is disconnected. Not sure about other question

My radio stations stay programmed in but I lose all my bass, treble, equalizer setting etc... I have never had a programmer so I cannot fully answer this question either.
