I have a 2003 Sport, (UK Spec) CRV with a factory fit, Alpine 2005 Sat Nav system fitted, running V2.06 software. It has recently started displaying 'DVD disc is reading an error' and failing to initialise. Has anyone had a similar problem? Would be interested to know if the problem is with the disk or the unit? Considering buying V2.07 software to upgrade, but pointless if unit is at fault.
