(Long - Read on for the symptoms...scroll down if you just want to see the solution)
OK! First off this I would not be able to post this information without the help of you all on this forum so first off...THANKS!!!
Having said that, I have been on this forum for about the past month since i picked up an AVIC-D1 off of craigslist. When I got it it only had the 2005 disk (east & west). So obviously i needed the 2009 info since i couldnt even find my street with the old maps.
After my initial install everything worked well but after about 2days i got the "please insert appropriate disc" message. So then i would eject/insert the disc three times and then the maps would pull up. I dont know why but for almost 2 weeks it would only work on the 3rd time. So after dealing with that i decided to order a disc off of ebay... here is the link http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=230339309526
The first disc the guy sent me did not work whatsoever. I used the change language procedure to do the update but got nothing but error messages every time. So i emailed the seller and he told me something about he had a bad batch of discs go out and would send me a second disc...it arrive about 3 days later. Once I got that disc i put it in and tried the language change...the update began right away! I finally had all of my 2008 info and was good to go...
that lasted about 4days 
...
After that point I would turn the car on and instantly get the "insert appropriate disc" message but this time i notices something stangely different...I could only get the disc to pick up if i was moving 
As in...when i was parked i could eject/insert the disc all i wanted to no avail but ONLY IF I WAS DRIVING AT HIGHWAY SPEEDS would the map come up and thats only after several eject/insert attempts. Over several attempts of this i kept repeating the downgrade/upgrade process but could never get the maps to come up the first time i cut the car on...
So I decided to make my own disc since that was the last option before shelling out the $120 that pioneer wants and this is what happened....
SOLUTION THAT WORKED FOR ME
AVIC D1 (US-Edition) + CNDV-80mt (West)
1. Found this link from TONTON - http://avic411.com/forum/viewtopic.php?f=1&t=23940 and downloaded the west version... SUPER BIG THANK YOU FOR HOSTING THAT FILE!!!!!!!! 
1a. I tried downloading it several times which failed cause my computer timed out...so i got "Dowload
Accelerator" took it from being an 8hour download to about 2.5hours http://download.cnet.com/Download-Accelerator-Plus/3000-2071_4-10037157.html?part=dl-10037157&subj=dl&tag=button
2. I downloaded WinRar to extract the file once it downloaded... Extracted it to C:\Documents and Settings\Desktop\CNDV_80mt_west and inside that folder was the CD image.
3. I downloaded IMGBURN next http://download.cnet.com/ImgBurn/3000-2646_4-10847481.html?tag=mncol . Selected the file in the folder above and set it to burn at 1x.
4. Went to OfficeMax and bought MEMOREX 5pk 8x DVD+R DL ($12.99) and burned the disk (took about 30 minutes).
4a. I have seen a lot of posts on here that say Memorex will not work but im broke and that was the cheapest
pack i could find lol...
RESULTS
Took the ebay disc out and put in the one i made.......
FLAWLESS VICTORY!!!!! Worked perfect on the first try (and parked may i add)!!!!! All buttons avaliable, No freezing on searches, Maps avaliable right away, and very fast operation.....
I just did it this morning so I will list any updates if something messes up but in the end all those steps seemed to have worked perfectly for me...so far (crossed fingers 
)
Hope this helps you...and thanks again TONTON!!!
