"please insert correct map disc" is an error in some Toyota voice navigation systems, Toyota cars made for the Japanese market.
A boot disk is required for resuscitation of regular navigation. After removing the battery the inscription "Please insert correct map disc" appears on the screen.

In less than a min, the Toyota map disc solution (software installation + 2 DVDs) should:
~ clear the "please insert correct map disc" error displayed on the car stereo deck
~ restore the touch capability, display, radio functions & access to the rear camera

nb: the solution only boots the deck and fully restores the multimedia functions of the car head unit.
