I have the same Problem with AVH1300NEX. Powers Off, then back on and remains fine ,Until I restart the engine. Happens every time, and the exact same Time frame after engine start. Pioneer said Might be a Firmware Issue.. Also had an Issue getting the steering wheel controls to work. ( Had to re flash the Metra Adapter.

Hi,

I'm having a similar issues I had a pioneer radio the Bluetooth setting vanished, the radio was replaced with another pioneer than a day later would switch off automatically wouldn't switch back on until by itself approximately 20 minutes later but then would stay off again. Had this changed to a Sony radio now doing exactly the same.

I have a somewhat similar question about my pioneer bluetooth car stereo. My audio shuts on and off going down the road. It makes a like scratching noise then it'll shut off then turn back on. Ive tried fuses,pulling the radio out and checking the connections, checking speaker connections,ect but it still continues to do the same thing. I have no ideas anymore.

Hi,

Does it happen when the car is stationary? Does it happen with the engine off? Do you have any problems with other circuits in the car that are fed off the accessories power e.g. cigarette lighter, power windows etc?

If it only happens to the radio with the engine on and more when you are driving it sounds like there is a loose connection or dry soldered joint in the power supply for the radio or in the radio.

You might have to connect a test lamp or DMM (digital Multimeter -Voltmeter function) to the power feed where it goes into the radio itself (or as close to the radio as you can get) to prove whether the problem is with the power into the radio or it is in the radio itself, i.e. either the power is on all the time at the radio power input point or it comes and goes.

If it is with the feed to the radio you need to check the wiring path from the radio fuse in the fuse block right through to the radio itself.

It may be for instance a loose connection at the rear of the fuse in the fuse block.

What type of fuse is installed? If it is a knife blade type check that the female connection point in the fuse block looks OK and that it has enough tension on the fuse. If it is a glass type fuse, again is it tight in the fuse holder, have you tried a different fuse of the same rating?

I have the same problem. There is power to the unit but the flip screen won't open or the whole radio has no power. I believe that it has something to do with the flip screen. AVH-X6700DVD Is there any way The flip screen can be fixed in the open position? I think this may solve the problem. I had this same problem with two other flip screen units, and was told they couldn't be fixed. This is in an RV and does not get daily use.

Hi @tlb

First , how long have you had the unit? If less than 12 months there is still a manufacturer's warranty on it.

If the whole radio has no power and you say that there is power at the unit, then if it is out of warranty the best thing to do is open the unit and see if there is either a fuse in the unit that may have blown, or any obvious sign of component failure like a burnt out resistor etc. If you have a DMM (Digital Multimeter) and know how to read circuit diagrams there are service manuals for the unit available online but unfortunately you have to buy them.

I have the same problem... but mine is a Lil different... if you switch on the radio the powers comes on, but as soon as you leave the on and off switch button, it goes off again by itself. What might be the problem

Hi @ Elton Ipinge,

I don't know your radio but if it has a push to turn on / push to turn off ON/OFF button, it may be that the button itself is faulty, in that the button contacts are made when you push it in to turn on the radio but do not stay operated when you remove your finger.

If your radio is no longer under warranty I suggest that you remove the radio and open it up to test the button's operation using a DMM's Ohmmeter function (Digital Multimeter) to prove that the button contacts stay operated when the button is pushed in and then disconnect when the button is pushed again.

I suggest an Ohmmeter as the whole button including contacts may be encased and therefore you cannot actually 'see' the contacts but have to prove it electrically, using an Ohmmeter to test for continuity through the contacts, most probably where they are connected to the circuit board. Do this with the power disconnected from the radio.

I have a problem with my 1999 porsche boxster. The radio comes on then immediately off at start up. After driving a few minutes it will turn on when I hit the brakes, use a turn signal, hit the power windows or just by itself. BUT it also happens with other accessories; like my electric convertible top won't work, door open alarm won't chine, seat belt alarm also.. Fuses seem okay, but I'm so lost on finding the problem. Any advice would be greatly appreciated.

Try bypassing the pioneer fuse/resistors in the pioneer wiring harness and then if it fixes your problem replacing it with a new harness from ebay,it fixed my problem

Can you send the link with the exact one you purchased on ebay?

I finally found out what was causing my problem,it was NOT the harness.It was the weakening of the metal contact springs on the faceplate connector.I finally cured it by easing out a couple of the contacts slightly on the end of the actual faceplate unit but it still causes me on/off problems on a regular bases.I believe only the replacement of the whole of the contacts part inside the unit (which i dont think you can actually buy) or a new head unit would permanently cure this problem

I have a DCH-P47DH that cuts on and off when I hit even a small bump. I get 5 high pitched beeps when it cuts out, then a single beep when it comes back so there's some sort of signal associated with the problem. I'm beginning to suspect the faceplate connector but no hard evidence yet. Everything else works.

My avh 201ex double din suddenly turned off once going to work like a 3 weeks ago. And just yesterday it turned on when i moved my car, but in the morning i checked again and it was off. I had already opened up the console and check for burnt fuses and loose wiring but everything seemed to be intact. I thought the stereo didnt work anymore but since it turned on last night, im guessing it still does. What can it be???

Hi @anhhung408,

If you’re using the Pinoeer ND BC8 rear view camera have you checked the settings as shown in the user guide -p.35-36?

Here’s an image of the relevant section.

Decibel settings are to high, and balance in left mid l, left mid and right also in right speaker does "Radio check it self if to much power is going to the radio", nothing wrong if cables are correctly connected. But to high amplified sound settings can make the radio to go off because to much power is taking out of the battery. If you set all 5 channels 100 decibels and 110 dB and 10 for the speakers,

radio settings can make the radio go off in till you disconnect the music source and set the settings correctly.

I have this same issue.. its in a vauxhall/opel/GM depending where your reading this. Originally it would flicker off for a second and lose all settings so was an issue with permanent live.. i needed to change the permanent and switched live over (Vauxhall idiosyncrasies) after doing this the same fault would happen but would not lose settings, so perm live is now steady.. i then added a tap wire to from perm to the switched live feed in order to give a steady 12v supply. As soon as i make the connection, cabin fans start up and stop upon disconnect.. same happens with the head unit so all working as planned.. however whilst driving the radio still loses switches live even though it has a permanent live tap running to it… really driving me mad now. Think the only option left is to get a new head unit and see if that cures it

I have a problem with my sph-da120. It get stuck on splash screen. Then turn off and it’s trying again. All the time. I checked everything except the memory card inside. Also the cooling fan looks like it doesn’t work at all. Or it is not turning on because the unit is struggling. Any help please ?

It could be cutting out because the fan isn't working and its overheating. May need to replace the fan

The problem is. We all have the same issue. Different car different pioneer head unit. My old one which I had switched out did the same. When driving the head unit turned off. My personal experience was if I hit a bump it turned off or on. After a month or so of this it stop working completely. So I replaced with an updated one. Not even two days it did the same however I notice for myself I was playing music with the volume up. It’s been a week and it been on 11 or 12 volume. No problems yet. Btw, I put heat shrink tube on all the wires thinking this can eliminate the problem. I checked the fuses as well. Any help would really help.

Thank you in advance,

I still deal with this same issue. At first I though it was heat related, however, it did this last winter on a 5 hour road trip. I have the Mistro unit per Crutchfield’s recommendation. It’s programmed and all functions work as advertised. My wife has the same head unit with no interrupted power issues. Hers only has an adapter kit for aftermarket to factory cables, no programmable unit between. Mistro may be the issue at this point.

I managed to fix it. My unit had a 4 gb memory card inside so I change it to a 16 gb and load the software on that one. Now it’s workin perfectly. Hope this helps.

To clarify, you took the repair access panel off to gain access to internal components? I have no slot access on the outside of my unit, unless this is the Maestro unit and I missed that feature.
