Hi everyone.

I'm in desperate need of some help please as i've killed the other 'alf's car 

I installed an Android based double-din head unit to replace the Swing head unit and was attempting to get it to power off with the ignition.  I pulled a pin from the connecting socket that had a '12V' identification in the wiring instructions but now i've plugged the head unit back in and tried to switch on the ignition (and was hoping this would provide power to the head unit only when the ignition was switched on) but now it's dead.....no lights on the dash when i either insert the key or turn it (to engage the starter).

I was thinking i might have blown a fuse while fiddling with the wires to the stereo loom but i've checked them all and none are blown.

Anybody any ideas please? does anybody know which fuse would deal with general ignition? 

Have you checked the fuses under the bonnet as well as those at the end of the dash?

I havnt.  Thanks for that Liger1956.....will pop out now.

A 15amp fuse under the bonnet blown, the good lady is mobile again now.  Thanks Liger.

Stereo dosnt work at all now.....but thats something i can work on in time.

Ok.  Finally found some time to try and get the stereo working.

I contacted the vendor who advised to put a ignition live to the red cable of the new HU and a ground to the black cable of the HU.  Did that but now get no power at all (fuse8 checked and replaced) .  I pulled the pins from the plug of the new HU to create ignition live and ground connections, would this cause no power? would i have to cut the car loom (where the red and black cables connect to) to create the ignition live and ground?  I've got a wiring diagram which shows the pins on the car loom having a 'canbus +' and 'canbus-', would these be the ignition live and ground that i need?  I've also looked at possibly needing one of these ISO adapter  would it just be easier to create new pins and put them back in the socket to use this?
 

There is no ignition switched live for the stock Skoda radio. It only has permanent power and ground, on/off etc is done over CAN-bus.

 

You'll either need to run a new feed from the fusebox or use a CAN simulator to create one

Thanks for the reply Langers.

I've installed a new live from the fusebox but i'm assuming then that the red and black are to be left in the plug?where does the new ignition live connect to? Whats a CAN simulator?where can i get one of these?easy to install?

Read the fitting instructions for your headunit?

 

I expect it'll need:

- power (permanent for settings etc)

- switched (to turn on/off with the ignition)

- ground

 

Where these will attach, is completely down to the headunit manufacturer...

 

It might help if you confirm exactly what you're trying to fit and add some pictures so we can see what you're doing/have done so far.

 

The CAN simulator connects to permanent power, ground and the two CAN-bus wires. It'll create a switched ignition live based on the CAN-bus messages it sees. Assuming the new live you ran from the fusebox is switched, there is no need for it

Sadly theres no instructions (or very minimal) but yes, thats what the vendor said. Yellow for memory,switched (red) and ground (black).  Its a YYKJ brand double din unit  

YYKJ Headunit.  I'll try and get some pics when its light outside.
