I have had my D3 for 3 months. This morning started the car and a Full screen message on a gray bar appeared asking me to "insert the appropriate disc. I tried both the East and West discs and it just asked me to eject that disc and insert the appropriate disc. Have tried pushing the reset button while power was both applied and not applied to the unit. No luck.
Anyone have any ideas? 
I just started to have this problem this week as well. I bought the unit at the end on May. After reinserting the dvd a good amount of times, it finally started to work again but it was temporary. I now get excessive vibration in the connection status screen. Speed pulse works on an off. Everything in the 3D calibration screen is showing asterix(*) and my GPS is having a hard time getting a signal. Oh yeah, I forgot to add the my unit will reboot on it's own and it will remove my backgrounds for the AV and Nav screens. I don't know what the problem might but it seems other people are having similar problems.
I also have this problem..
Do you guys use the original dvd? or dvd that you burnt by yourself??
I am still using the original DVD without a scratch on it.
Has anyone figured out what is causing these problems?
My D3 just started doing the "Insert Appropriate Disc" act tonight out of the blue. I pulled in to a gas station, turned the car off, then turned it on to leave and that message popped up. I've turned it on and off many times, and did a hard reset using the button on the face with no luck.
After being frustrated for a couple hours, I went back outside to mess with it some more and it booted up like normal (with the disc still inserted) and everything seemed fine. But then the time changed to all asterisks (*) and a message popped up saying something about no GPS signal. I turned it back off, turned it on and now its back to the "Insert Appropriate Disc" message.
Has anyone contacted Pioneer about this problem?
I've been having the same problem off and on for about 3 months. Now it only works about once every 7-10 days. Of course, I'm out of warranty. Desperate for answers if anyone has one.
Did you try to blow some compressed air into the loading slot?
Did you try to blow some compressed air into the loading slot?
No, I haven't tried that yet, but I guess it can't hurt considering it hasn't worked for at least 2 consecutive weeks now.
hi there,
the answer to this problem is that someone tried or install newer version of maps that you are trying to install now that's the reason for that message.It doesn;t have to do with dust, or scratches on the original disk.
This answer Pioneer gave to me.
Did anyone have the CNDV-80MT Europe verion?or know any torrent?
i'm in the same boat as all you guys. D3 worked perfect for about a month, and suddenly froze up one day while driving. Did reset and tried putting the disk in a few times and nothing just freezes up and i have to turn it off and turn it on and press eject repetedly to get it out. No upgrades using factory disks. Any new info on this problem would be awesome.
So do we have to get the upgraded/newer East and West navi disk so that the "Please insert appropriate disk" would go away???
Wow I am suprised so many ppl have the same issue. I just started getting this. I noticed that the time on my unit was **:** so I turned off the car and back on to powercycle the unit. When it came back up I get the insert appropriate disk message as well. I haven't tried to update anything, and the DVD has been in the drive since the moment I got it . I don't don't switch it out for anything since I have an ipod.
I get sound via FM but the screen and menu buttons are non responsive. I have had the unit about 14 months now, so I am out of warrenty as well.
Sounds just like my problem...
I just removed the unit from my dash and went back to stock. I did get it to fire up breifly and went to the Hardware screen, the device mentions excessive vibration and that I should contact my service center.
I called pioneer, I need to send it back with a 200 dollar check if I want it repaired. I don't like the D3 enough to get it fixed. I think I am going to just get a Nuvi, I considered a F700BT but if it's anything like the D3 it aint gonna last long.
hi there,the answer to this problem is that someone tried or install newer version of maps that you are trying to install now that's the reason for that message.It doesn;t have to do with dust, or scratches on the original disk.

I'm the only one who has ever used this unit and I never installed nor tried to install any map version other than the original maps that came with the unit.
I brought my vehicle back to the place where it was installed. They removed it and reinstalled my factory radio. They've shipped the unit back to Pioneer for repair. It's out of warranty, so I know I'll have to pay. I'd hate to scrap the unit, because I also have the satellite radio and bluetooth accessories. I'm hoping to have it repaired for a reasonable amount.
I'll let you know how it turns out.
I just got my repaired D3 reinstalled into my vehicle. Even though it was out of warrantly, Pioneer covered the repair. I had brought it in to my installer once during the warranty period because it had locked up on me, so I guess that was considered the first complaint. It only cost me $45 total. (Removal of D3, install factory, remove factory, Install D3). This thread hasn't seen much good news on this issue so I thought I let you guys with similars issues know that it can be worked out. 
after reading this thread i noticed that my time is shown as **:** also. it doesnt do anything else though the dvd works fine and the navigation screens says insert appropriate disk but only because i dont have the disk yet to put in it
OK so here is what you need to do to fix this. Buy the Pioneer Remote for the head unit. Hold Down the Eject button on the Head unit then press the reset button. Keep holding down the eject until "Please Press the Reset Button" displays on the screen. Then make sure the remote is set to DVD then enter 81837208 and press Enter. Some head units will automatically go to the next screen without having to press enter. On your Remote 2=up / 4=left / 8=down / 6=right / C=Back / 5=Select / 7=Navi . Go to page 2 using the right or left keys. Go to Program Forced Write. Anything that displays NG is corrupt and or not loaded. Select GPS Program and then Select CD/DVD you should see Version 1.5. If not your DVD drive is bad or You have a bad disc. Anyways select the DVD drive and press the Navi Button "7". This will force the map Data Download. You will see a % bar Come up once it hits 100% you are all set . DO NOT HIT THE RESET BUTTON Turn off your vehicle and open the door to turn off the head unit. After this turn back on your head unit and everything will boot back up like normal. 
People if u have a bad disk or want to down grade, just go into the language settings and change it to spanish or french and once it reboots put the disk in that u want to run the d3 with and when it reboots change ur language back to english or what ever laguage u speak, it worked for me. 
Some updates go so baddly that you can not get into anything. None of the side buttons work but eject. There is absolutly no way to do as you are saying by going into the menu. For this case you need to buy the remote.

This is what you wrote on a reply on Dec 11th
I decided to update to new maps and now I constantly get "insert appropriate disk"
I did all the searches and found how to get into the service menu and when I view the "version check" it lists the current versions. System program, Application Program, but under GPS program it lists NG. I have tried numerous times to force write the GPS Program. When I attempt to force write it, it shows...
1. PC ATA Card = NG
2. Disk = Version 4.40
So I click on number 2 and hit the map button to force write the program and it starts for about 1/10 of a sec then says....
DVD - Flash [ ng ]
I have tried to and succeeded to downgrade the programs back to the original disk but it never works for the GPS program it just shows NG. It does work for the System Program and the Application program.
I viewed each of the disks and and can see the neccessary gps program on the disk but just can't get it to load onto the unit.
Any help or suggestions would be greatly appreciated. Thankskcaxt

Then you wrote on the SAME day:

So as noted above and you see the version (1.5) and the install bar go to 100% but you also see the NG and it does not change.....what issue is holding it back from upgrading. I followed your instructions, and as said , saw the version 1.5, saw the loading bar go to 100, but still it says NG. You said on you in the first reply that you had the same problem. Did the procedure in the second reply get rid of the NG? And what appeared?
Hello,
I have the same problem.
But how can I change my language?
My radio and ipod function works.
But if i go to navi menu it gives me: Please insert appropriate disc.
Ok im here to join everyone with the same problem i tried everything from this thread including disconnecting the battery for 10 mins and nothing please help find a solution.
Yes I have the same problem the only way to fix this is to sendc in your head unit to pioneer witha flat fee of $200 and they will fix it. If any finds a solution let me know
