Car radio switches on/off at random - possibly OT

Nov 14, 2008 32 Replies

If this is OT, does anyone know where I should post?



My car radio/cassette player has taken to switching itself on and off at random, even when stationary with the ignition turned off (this latter drains the battery). Since it doesn't lose the security code when it switches off, I feel that it cannot be losing connection to the battery. I have, of course, removed it from the car.



Has anybody seen this sort of behaviour, or have any good ideas. I'd be grateful.

Don't even waste the time & effort on it. Just lob it and get a new one from one of the online suppliers - caraudiodirect or incarexpress or similar.

We chucked a new Sony radio/CD/iPod head unit in 'erselfs car last year for £80.

Until I read about it doing it when stationary I was going to suggest an ill fitting removeable faceplate if it had one .

Are there any wiring bodges?

A common wiring problem is the red (power) and yellow (standby power) wires shorting together, deliberately joined or transposed.

That may be easier said than done. Modern cars tend not to have standard euro sized radios but things shaped and sized to fit the dash, at least on the outside.

I'd look for an intermittent supply connection fed via the aux position of the ignition switch, (loose/corroded fuse). There is normally a separate supply to maintain the memory/code.

ITYM "Memory" and "Ignition live"

Joined isn't a problem - you'll just have a head unit that can be used with the ignition off. Shorting together'd just get you a head unit that might sometimes stay on or come on when the ignition's off. Transposed will just give you a head unit that can be switched on when the ignition's off, but only keeps the memory when the ignition's on...

(Assuming, of course, there's no way for the ignition live to feed back into the rest of the car's electrics.)

...and cheap and easily available facia adaptors...

Never thought of that. Just what I need for my van. Do you have any recommended suppliers (I will also of course Google myself)

your gonna be mighty pissed off when your new headunit displays the same symptons tho if the fault it the wiring in the car.

bit like saying put a new engine in the car when you have a blocked fuel filter :)

It's not quite that simple. Many these days will work for a timed period with the ignition off - for when you leave a passenger in the car, etc. Mine does.

Only those I gave in the first reply... CarAudioDirect & InCarExpress.

Which is most unlikely.

Still that simple - a permanent live, and an ignition switched live.

Without the www. before them I missed them. Point taken and thankyou

Any ideas on keeping the top display working, the one with the time, temperature and radio station with a new unit.

"ARWadsworth" gurgled happily, sounding much like they were saying:

You can get display & wheel remote adaptors for many head units.

Don't spose you know where I can get a basic cheaap car radio, don't want CD, DVD, I Pod, just radio?

On my old Renault, removing the old radio just removed the radio station display. The time & temperature still displayed OK, and I just ignored using the stalk controls.

One of these, perhaps?

Do they still make 'em? When name-brand MP3/CD/tuners with RDS are less than £40, why bother?
