Can anyone help with advice on getting my Nav Unit to be able to unfreeze to allow
me to enter a destination. I have the ver 7.1 disk installed and was installed by the
Lexus dealer, however, they are trying to tell me I need a new ECU. At first the DVD
would not load and they stated to replace ECU because it wouldn't read 7.1 disk. I told
them to unplug and plug back the ECU power supply and it then was able to read the disk.
Can anyone help me!
