08 xc90 navy screen say insert disk - Cars & Trucks

you did not list year.
google ( insert year) volvo xc90 fuse diagram

the whole unit will have to be removed and disassembled.

check the sa/nav fuse in engine compartment. may be blown. or sat/nav dvd reader is in trunk of car on passenger side above wheel arch, unscrew holding screws , disconnect power cords at rear, & get unit checked. it may be finished. can repair or replace..both expensive.

Check for a scratched or dirty Navi DVD disc. Clean or have the scratches polish out at your local game store. Video game stores usually have a disc repair machine that polishes out scratches.
Note: In some cases the Navi unit can cause rotational scratches on the DVD. If this is the case than the Navi unit will have to be replaced.

i have the same problem with my 2003 volvo, did u fix it?

The old style sytem has the DVD player in the rear of the center console, the newer style has individual players in each screen. There is a small tab at the bottom of the screen, push it up and pull out, the bottom of the screen will tilt out and you insert the DVD up into the back of the screen.

I had this problem as well in my 2005 XC90. It turned out that it was switched on audio. Use the remote to switch back to DVD.

I've reads post here suggesting disconnecting the battery for one hour. Couldn't hurt to try it.

Also try ejecting the Navi Disk, inspecting it for any damage, wait a few minutes and reinserting. The disk contains not only the navigation Database, but also part of the operating system.

DO NOT TRY INSERTING A OLDER NAVI DISK OR ONE FROM ANOTHER VEHICLE, THAT COULD DESTROY THE NAVI UNIT!!

If you need a new Honda Navi Disk, order it direct at https://www.hondanavi.com/Hondadvdsales/naviorder.php

Good Luck

Unless it has been stolen, it is unlikely the disc is missing.

This disc the error references comes installed inside the navigation unit that is underneath the driver's seat.  There is absolutely no reason to pull the disc out, unless you are replacing it with a newer disc.
  It is possible to accidentally hit the unit with your shoes or while vacuuming the floor in that area.  Check under the driver's seat and make sure that the unit's door is not open.  If you still have a problem, then open the unit's door all the way, press the eject button and check the disc for scratches. If no disc comes out, then you are definitely going to need a replacement. If a disc comes out, check it for scratches and reinsert it if it looks ok (as it should).  Then close the unit's door and retry to use the navigation system.

Heres what you should do:
1. Start up vehicle.

2. Hold down buttons: MENU + MAP/GUIDE + CANCEL for 5 seconds, (the "Select Diagnosis items" screen will appear) then do the following:

3. Hold down only MAP/GUIDE (again) for 5 seconds (A screen with a "Complete" button, will appear).

4. Tap the "Complete" button on screen, and then the "Return" button.

5. Restart vehicle. Everything will work! That screen won't popup anymore! =)
