Ok How do I do this for a Z2/Z3? I have files moved to a folder called pictures, Burned it all to a CD ROM with lots of other files (my entire pic library) the upload pics button is still greyed out however. Help me crack the code. I was able to modify my wifes D2 with PIMs and the ISO procedure. This should be an easier process with the Z2 as all the formats are JPGs or jpgs correct? What Am I doing wrong? Did I miss a page in the manual???
Help
To close this post out (maybe a MOD can make a sticky?)
I figured this out myself
You need to create a CD-RW Disc
Make sure all the pictures you want to load are in a JPG or jpg format only
Make sure all your pictures are 500X240 in size so they will fit the screen
Create a folder called "Pictures" and put in all your picture files in that folder
Now load 100Meg of junk files onto another folder on the ROM your about the burn or your DVD will not be able to read the CD properly. Dont put more than 8 directories on the disc!!!
Do not use any MP3s or sound files as part of your Junk data (important)
Now you are ready to burn your Disc, make sure you select complete in one sesson option. If you dont load it up with 100meg of junk files this procedure will NOT work.
Take completed Disc and load it into you HU
Press Menu then Settings then change background pictures
Choose load from Disc function. You have three screen options for a background change. The splashscreen, Av Background and Nav Background
Happy motoring. I wish somebody had taken the time to tell me how to do this last week. GC
Stickied by request. 
PS, the middle post was removed to push up the instructions closer to the top.
Thanks just trying to hook the next Z series owner up. GC
is there anyway to keep these backgrounds on the HDD?
is there anyway to keep these backgrounds on the HDD?
I read somewhere there is a way. However that work crosses into seperate partitions on the drive. Never done it myself again this is what I read somehwere here on the forum.
Are the screens loaded into a non-volatile memory vs. the HDD?
Yes. They can be stored on an unlocked hard drive (while connected to a PC). When you select a particular background, it is copies to the AVIC's internal memory.
Does it have to be a CD-RW or can I use a CD-R?
You can use a CD-R but that's a waste of a CD in my opinion.
Understood but I own 100s of CD-Rs and no CD-RWs so I'm not going to run out and buy a RW for this.
Well game on.
I must be doing something wrong i try to load an image from Nero and my system doesnt system to find the file and the Z1 sayes Disk unreadable?

If your system says Disk Unreadable, and you're using a CD-RW, your disc may be going bad. If you're using a CD-R, you definitely burned it wrong.

I have attached the 3 pdf pages from the owner's manual on how to burn and install backgrounds.
Garret if it wouldn't be too much trouble could you also post instructions on how to load backgrounds onto the hdd, and then access them from the unit? I tried doing it myself but the only way I can get them to load into memory is by going the CD route, but I'd like to just load them once onto my hdd and be forever done with it. Thanks.
You can't just put them in the same folder as the other BMPs?
There are a lot of ways to put them directly on the hard drive, but I don't recommend anyone to do this unless they know how to reimage their hard drive (just in case). I have not done a lot of research but this is what I DO know, and how I do it:
Hard drive MUST be unlocked.
Image must be BMP format 500x240 pixels and 24 bit color. File size should be 351kb.
Images can be saved on the LDATA (map partition):
LDAT\BG\PREINSTALL
By default, there are 15 preinstalled backgrounds. I have tried to put more than 20, but that does not work. If you want to add more than 5 custom backgrounds, then you need to remove some of the stock ones (so there are 20 or less in this directory). I have added a directory called 'stock' and I move the factory images rather than delete them. You can not select any images in the subdirectories, but you can store them for later use.
This is what I know at this time. If you have time for more troubleshooting, please post your results.

Did you follow my directions? If you dont have 100Meg of junk files on the CDRW when you burn it in one sesson it wont work. GC
Thanks "ALL" for the info on how to do this. 
Works perfectly
Your welcome I was confused at first as well
Can you manipulate imported background pic to fit screen similiar to strecthing to fit the screen on a PC?
The only way that I know to do it is on the PC. Either resize/stretch/shrink/crop/etc to make the image 500x240 pixels. I use windows Paint.
Please help.
I'm using a CD-R (I've tried a few). I have loaded 2 of my own photos and one from this site into a directory called Pictures and I have added a data file greater than 100MB to the root. When I put the disc in the Z3 it recognizes the disc (Checking DISC msg) and it finishes with a message CD-ROM Inserted. However the button to load the images from disc is still not available.
Is the problem a result of the disc being "CLOSED" and not "FINALIZED"? What else should I try?
