You do not need any tools for this. And the diagnostic info tells you a lot.

Hi Swiss xc90.
No, the unit is to all intents shut down, I cannot get it to light-up at all, as I said the only action I can get out of it is to wind the dash display up manually then as soon as I reconnect the power it immediately powers down. I have tried pumping the back and enter buttons on both the steering wheel and the remote control but it refuses to respond. |

That's a shame. If you really want the nav to work, you need to determine if the screen or the nav unit itself is at fault
Just because the screen motors down again, doesn't mean that the screen is fully functional. Note that nav units are coded to the car and a replacement second hand nav will need the flash memory overwritten with your flash memory contents - something only an electronics expert can do.

Thank you for your swift response I really appreciate it. I don’t have Vida or DICE. I took it to a Volvo dealership and they gave me the code. They want me to book in the car for a further 2 days to “diagnose” it. I must pay them a fee to diagnose it and only afterwards they will “quote” me to fix it. So basically an arm and a leg.
I’m thinking of taking out the amp out to inspect. Hoping it is really something simple. |

VIDA tells you how to do a ring break diagnosis. You can also temporarily bridge the fiber optic line of a suspect bad device to determine if the ring comes back up. I suggest asking on this forum for anyone with VIDA who is located close to you. I'd happily help if you come to my house, I live in the original CrossCountry, in the alps in the middle of Europe

Thank you so much. I really appreciate the assistance.
I stay in South Africa, so sounds like an amazing road trip that requires a few ferries - see you in a week or two lol. I’m hoping I can get access to the diagnosis tools. Will keep asking around. I have a good feeling that the issues is at the amp because I don’t see that fibre light coming out from it. |
