Strange Uconnect problem

Hey everyone. Just got a 15 Willys Wheeler. Still figuring everything out... And can't seem to add pictures to the uconnect system. I have the 430 w/o nav. I have searched but haven't seen a solution to my specific problem.

I can load music just fine from USB. I can almost add pictures. I can go to the add pictures screen and it even shows me the thumbnails of the pictures - so I know it "sees" them. I check them to add them to the hdd, and I get an message that says there was an error copying the pictures. I've tried over and over. Different USB thumb drives. Verified FAT formatting. Played with image resolution (even using the recommended resolution from the manual). Images are jpeg. Nothing works. Again, mp3s load fine. Although... I get no album artwork, but Im not sure yet if that is expected.

Any thoughts? Every post I have seen is that the USB can't be read at all... I just have a picture import issue only.

Re: Strange Uconnect problem

I am unsure of exactly what you are referring to but I had similar issues with my uConnect. The pictures were not displaying on my 8.4A because they seem to have exceeded some size limit. When I reduced the picture size all was good

Re: Strange Uconnect problem

I've got the file size down super small, and it didn't make a difference. Thanks.

Re: Strange Uconnect problem

I know on my 730N, the pics had to be a very specific size (240x158 pixels). Mine were also in the root directory on my flash drive, but I don't know if such is required.

Re: Strange Uconnect problem

Done both of those things. Root location and specific file size. No joy. I took some pics but can't upload them from tapatalk... So I'll send them up in a bit.

As you can see....simple jpeg using recommended resolution.



UConnect sees the files fine, and I select the one image that is the specific size.



And...here is the error...

Re: Strange Uconnect problem

hmmm... I guess I am the only one with this issue. Explains why Google can't find me the solution. I'll see if I can get a hold of someone from uconnect support or something.

Re: Strange Uconnect problem

Okay...interesting...was able to load a couple of random pics onto the system. One...fairly large picture from a friends camera...two...random photo from internet (large). So whatever my problem is must be specific to the photos I am trying to use. It seems that getting the specific resolution isn't the issue, nor is having a specific small file size. All photos I have tried have been made in Photoshop, or downloaded from Facebook (easy to find my personal pics there). So not sure if there is something about those two things that uconnect doesn't play well with. More to come.

Re: Strange Uconnect problem

Could it be interlaced vs progressive jpg?

Re: Strange Uconnect problem

SOLVED!

And...WaltA...progressive wasn't actually my problem, but you are correct that that matters.


Here's what I thought mattered:

Resolution
File Size
Location of the file (root of the drive)

Here's what UConnect Support told me that mattered
Resolution
Thumb Drive Size (MUST be between 4GB and 32GB only)

Here's what I found that *really* matters:

Color Profile
NOT Progressive

USB size didn't matter for me, I can use both 64GB or 2GB (both outside of the limits given to me by UConnect) with the same result (positive or negative)

Resolution and file size don't seem to be as important as I thought, although there may be some limitations I haven't tested...but I put pretty large and oddly shaped photos up just fine.

I was successful adding photos from a folder, or straight from the root. That doesn't seem to matter.

I did NOT have to have MP3 files on the drive (I read that some people thought that was required.)

I basically found two independent circumstances that would fail - in different ways.

First, if you aren't able to "see" the pictures in the thumbnail view on Uconnect when you are trying to add them from the thumb drive, it is likely that "progressive" setting was used for the image. I didn't originally have this issue, but tested it after WaltA's comment. Gimp, for example, defaults to "progressive" images for jpg, and you have to go into the "Advanced Options" part of the export dialog box to uncheck. That should help some people who can't even "see" the pictures on Uconnect.

Second, if you can "see" the pictures, but get an error importing them, then check for embedded color profiles. This was my problem. I have some advanced color profile settings in Photoshop that get embedded in my images. I have NEVER, and I repeat NEVER, had a problem with compatibility using my color profile (sRGB IEC61966-2.1) with any computer, upload, or device. Until now. When I take the same picture and just change the color profile to a standard sRGB profile (the non-International sRGB), the pictures import just fine in Uconnect. This explains why my problem is unique...most are probably not using photo tools that embed this profile into the images.

So there you have it.... two solutions to two very different problems. And several "factors" that turned out to be a non-issue (at least for me). Hopefully this will help someone in the future who is banging their head against the dash because their imports keep failing.

Thanks for all of the ideas and help.
