Just bought a 03 Ulysse all working fine, until 3 days after when driving along and everything went dead long story cut short, took back to dealer replaced a faulty battery and fuses which seem to be ok. But now a week later we are having problems with th RT3. 2 cds were stuck in there, the sat nav and a music 1. Got my mechanic to disconect the unit take the discs out, when we put it back in, radio plays multi disc unit plays but there's no sat nav or any other display apart from the fiat logo. In the bottom right corner reads loading, starting, reading. By reading some of the forums i am at a lost with what to do. Do i have to press the DARK button or take the battery off for 30 secs or do i have to go and see a fiat/citreon/peugeot dealer???????
