I tried updating my 02 Rx300 with a new navidation dvd (6.1), but had some problems so I wanted to go back to the original version (2000 v1) that was in the car when I got it.
Someone said to disconnect the battery for 10-20 minutes and then reconnect the battery (this is suppose to reset the navigation). I then turned the car on and got the screen saying it was updating the navigation, then after a few minutes it came to the Caution screen, then I got a message saying Disc Error, check Disc.
I tried this process again leaving the battery disconnected for about 40 minutes and got the same results.
What do I do now to get my navigation working again?
Please help!
Thanks
Ken
