2005 Toyota Sienna XLE, 97K. Navigation screen shows "Unable to read CD map" since last year. Replacement cost with a different brand $1.5K and I will see spaces around the unit. Decided to not have the GPS, since I still have the radio. 6 months later, problem with the radio. Radio will stay on whatever station and sound volume set after few minutes of driving. Had to turn off the engine and restart, to change radio station and sound volume. 3 months later, after backing up and driving forward, screen stayed, as you back up the van. I have an extra view of what's behind me while driving. My car battery got weak today and got replaced. My screen now shows "No CD map". I am unable to reject the CD map inside the unit. I still have my radio. My screen depends on whatever the mood of the car at the time I start the engine, "Unable to read CD", "Insert your DVD map", the back view or the warning message waiting for me to touch "I agree". Got to re-start if I want another screen to show. I will check with a toyota dealership for refurbish swap as mentioned above. But if it cost a lot $$$, I will stick with my current radio until it quits on me and hoping, by that time, there's a solution posted by others on this site.
