Ignition On, Stereo On?

[CinqyAbarth]

Hi guys/gals

i bought a sony m630 cd player off a friend with blackout feature etc etc, when he had it in his Pug 306 it flipped open and turned on when he turned the key, and went off when he turned off the ignition.. I want to do this in mine, it currently stays on all the time...

1) so if i press off once sony and a red light show in the top left corner, (this way i can press source on the remote)

2)if i turn it off completely by holding down the off button it goes blank and i have to press the red button so it flips open and press source so it turns on (but cannot use the remote until i do this).

Its not urgent but these HU's have faulty buttons and sometimes the source button closes it up again :bang: so it can take me ages to turn it on.. and i dont want to leave it on all night when im at my gf's as the chavs would have a field day if they saw my stereo, then the subs etc lol.

I have read a few old posts, (and slippys sticky) but i cannot make any sense whatsoever of them. Can someone help me please?

ps I have a Cinquecento Sporting and it is a Sony CDX-M630 HU.

pss sorry for the essay!

you need to find yourself an ignition on only power source, then wire this in to the red wire of the ISO block

cheers for the reply luke, an ignition only source close by would be...?

Now thats the multimillion pound question The nearest one i can think of is the power source off one of the electric window switches

If you've got a multimeter, just turn on the ignition and then probe about with it finding power sources. when you find one, switch off ignition and see if it drops voltage. If it does, bingo

thanks mate, will see if it works later

You *may* find it could pop the fuse for the window switches. if this is the case, you simply need to get yourself a relay and use the window switch power source to switch the relay, then use a fused feed from the battery/12v constant power feed

oh my now this is getting complicated lol. ill just have a go at the window switch thing, and get dad to fix anything i break! or just leave it broke

If it does, just say relay to your dad - he'll probably know what i mean If it works without, let me know - i need to do something similar within the next few days

ok and on the same basis of i try it first.. if i break mine, then im allowed to break yours?

As far as I'm aware Luke the activation 12v just flicks a relay (well probably a logic controller) within the head unit. The actual amount of power used down that wire is very low. Fuse poppage should be very low risk. Do I take it that the ciggy lighter is always live (if you have one) in a cinq? They're switched by ignition on bravo/marea so I'm guessing Sei too for that change.

yea I was just saying in a worst case scenario Main power comes down the yellow memory wire, but in some headunits they draw lots from the red wire too
