Ok so I just bought this car today and the previous owner stated that the car died and ever since then the nav system has been acting up. I've been troubleshooting now for about 10 hours now trying to find the best option. I've cleaned the disc I've disconnected the battery and let it sit for 15-20 mins and even touch the cables together to reset the whole system. Now I'm down to a few options of cleaning the eye of the nav drive by completely removing it and tearing it apart and cleaning it manually or find a drive cleaner disc that works for this nav drive if that even exists? Or taking the risk of buying a whole new nav drive and installing that. Also from what I've heard Alpine no longer services these systems... I'm running out of options. Any suggestions?
