Hi all!

Recently bought an aftermarket single din stereo to replace my standard Delphi and I'm struggling (one thing I suck at is electricals). I purchased a fascia and iso block as a bundle for the new stereo to hopefully "plug n play". I tried that and no luck, I moved the pin location on the adapter for the yellow wire to line up with the standard location on the factory iso block. This caused an airbag fault to come on whilst ignition was on. I switched the bullet connectors for yellow and red and this did nothing either.

Any help would be greatly appreciated as I'm losing my rag very quickly! Hopefully I can add some photos of the current arrangement I have going on! (Each method I've done fails to even power the stereo).

Hope you've already got it fixed by now but here's the answer anyway: The new Fiat Panda uses a canbus system so it needs a canbus interace to turn the stereo on and off. Instead of the iso block you bought, you need something like the Incartec 20-101-IGN interace. I got one of them off eBay for my Panda and Pioneer head unit and it works great.

Oops! Sorry, thought I was on Panda forum! Anyway, it looks like recent Puntos have same canbus system too.

The iso block is fine, you just need to connect your live and switched live to something else. You can get a permanent live from the fuse box, you can get a switched live from the cig lighter socket.

You must not connect the red and yellow live and switched live wires to the cars original wiring loom because that connects them to the cars canBus system that cannot supply the power but also you can end up shorting the canbus wiring
