Siemans NCDC 2015 Car Radio/Sat Nav/Telephone/ CD player

Radio switches itself on at any time, day or night. It is OK when driving because it can be switched off but at night or when parked it draines the battery. The Vauxhall garage answer is a new unit @£1500. can you help.
Note: At times it is not possible to switch on but usualy comes on at the 2nd or 3rd try. Is there an exchange deal anywhere? ( not with Vauxhall)
Is it possible to take to a Siemans Repair agent in UK?

Heres a question....does the main power switch "feel" like the others.

The main power switch is one of those that gets a workout. After looking at some images, I am going to guess that it is what is called a "Tac" ( short for tactile ) switch.

How do you tell if it feels right?.....go to the least used switch on the unit ( is should theoretically be like new if it is the least used ) ,and very slowly push it in. What do you feel?....some resistance and then it gives? you hear a slight snap ( make sure the unit is off or the volume is all the way down ). Now go to the power switch....does it feel the same ? A sign that ths switch is finished is that there is no travel to it, that is, when you push is it stops immediately....the least used switch should have a little "room" in it before it hits bottom and makes the connection.....I'll bet the switch is shot.......give it a go......Thanks..Rob

If you can feel a big difference in the switches, then I would take it to a local electronics shop and see it they can replace the switch ( those type of tac switches are EVERYWHERE ), or maybe find a seimens shop and have them look at it.....better than 1500 !!!!

    No Sound from Jensen VM9725BT

    Jimmie Monica Hey, Its not a problem with the unit. You have the blue or Blue/White wire hooked up wrong. Disconnect both the blue wire and the blue and white wire and I guarantee the sound starts working on everything. If you have one of those two wires hooked up for a power antenna or remote amp turn on, then switch which one you are using and that will fix the problem permanently. Disconnecting them both will get it to work though. I guarantee it. Please post back and let me know if it works for you. Thanks

    Denon AVR-2309C1 will not play sound through

    Turn off zone 2 then turn your receiver on the main zone on Radio, tune in a station and check for audio. Post a comment and let me know if audio works that way. If you don't have any audio, list your other equipment makes and models as well as how they are interconnected to your receiver (cable type) and I will help you troubleshoot

    Dear Tech, my Dual XDMR 7700 stereo/cd player is giving me a hay day. When I press the open button on the faceplate, the faceplate drops down and goes right back up. I can't even load a cd in to the...

    Most of the time these radios with the displays that move up/down have a ribbon cable that may go bad and cause funny types of problems. I can not say for certain what is causing your problem withour putting it on a test bench and troubleshooting it with the proper equipment. It may also be a swtich the detects when the display has reached its open position. If the switch is bad, it may just close right back up again.

    But the ribbon cable is a good start, since it gets some wear and tear every time you turn on the radio.

    Peugeot 406 cd player works when ignition is on but when engine is started cd player wont work. Radio is fine.

    Just bought 2001 peugeot 406.The radio worked perfect but CD player not reading disk or operating.That was until I realised that the CD for driving safety will not allow you to put CD into it while driving or engine running.Switched off engine then switched it to 1st batt light position & CD worked perfectly.But when I then switched key off & then started it was back to not operating.I then realised that the CD player for safety will not operate when engine is running unless you let the CD start operating first pre engine fire then wait a little more time before starting .Now it should work properly though it will not allow even the passenger to change a disk while being driven. On disk change you have to go through the same start proceedure.Hope this will get your CD working.Sherlock ??

    Vauxhall astra radio keeps switching on and off on its own

    I had this problem for the last 2 weeks, didn't think much of it, but recently the car radio just turned on and off by itself, it decided to do so whilst the car was switched off and it drained my battery. After doing some tests with the Amp meter and removing the fuses for the radio and infotainment system the amps going through the batter went from about 0.7 to 0.001 (far more accpetable) - so the radio was draining the battery and randomly turning itself on/changing stations and the internal display system had stopped working.

    after putting the fuses back in and re-testing the radio worked fine (almost like it had a full reset - no random turning on and off OR changing of radio stations)

    the fuse box for my astra was next to the battery under the bonnet (see your car manual - I had lost mine so googled for it)

    PAGE (267 or 265)

    but it seems yanking the fuses for the radio (FUSE number 35 and 36) seemed to fix it (been a few days and no flat battery) -

    It maybe an intermitent fault, in which case i'll have it looked into, but as garages charge an arm and a leg i'd give this solution a go and if your battery is good all you need to do is remove the fuses and put them back after say a minute or so)
