Technical Stereo says "No Can Network"

[stumacd]

Wondering if anyone can help. My 2007 Fiat Bravo 1.4 Active Sport has a bit of an issue with the Radio/stereo.

When I switch it on it says "No Can Network" and counts down 5, 4, 3, 2, 1, 0 and nothing happens.

I removed the stereo and checked the wiring which all seems fine and also checked the main stereo fuse and the one in the fuse box which were both ok.

Any help would be greatly appreciated.

You have 2 options: either the headunit is faulty, either the wiring for the CAN is.

I would download the eLearn software, then write down where those 2 wires for the CAN actually connect to, then do a continuity test, (!!!!! BATTERY CABLES DISCONNECTED!!!!!!!!!) Y

I will download the eLearn software and have a look.
