Hello

My car, Golf 5, doesn't have +12 ignition wire, only the +12 permanent.

Can I get it from the permanent wire with a switch like this?

I think the answer is no because the radio starts to heat up but I dont understand why.

Can somebody explain it?

Thanks

Have you put in-line fuses in your wiring for the power lines?
You may have wired it up incorrectly and the radio is drawing too much current.

I'd be surprised if you can't pick up an ignition live from somewhere. Have you checked wiring diagram and fuse box details?

As Spoon says, make sure any supplies are fused.

approx 1/2 the fuses in the fusebox are ignition only. try the rear screen demister circuit or fag lighter.

There is definitely an ignition live available,but you may find the audio is canbus integrated. There are conversion kits available,or you may find weird things occurring,like the radio turning off every hour,etc;)

Yes, there is canbus with weird voltages like 11v and 2v through tiny wires.

I think it's cheaper to just pull a cable from the fuse box.
