U310BT Won't read SD Cards

Ok, I've tried two different cards, formatted both several times, and have tried loading POI files from the feeds app (what a poorly written POS that is), with no luck whatsoever.

Likewise I've tried putting the TTS voice files on the same cards, no luck there either.

And finally, I tried putting the firmware update files on them, still with no luck.

For whatever reason, it appears as though the unit refuses to acknowledge the presence of SD cards.

I've tried formatting them on multiple computers, with 3 different card readers. In all cases, the cards show up fine with the files on them to any computer I try (including Macs).

Any ideas as to what may be wrong here?

Hopefully your formatting the cards with fat32 or it won't read!!!!

I'm having the same problem, it appears that the unit is not recognizing the SD card, although the "Eject SD" is bold, the "Cpy Setting" is not bold. If I'm reading the manual correctly that is the function you use to import settings from the "Avic Feeds" utility. I used the "Avic Feeds" settings replicator to save a file on the SD card. I also reformatted the card with Fat 32 and tried again, but no joy. The card had worked previously to do the update, so I don't think its the SD card. Can someone point me toward a solution?

I figured out the problem. The Avic Feeds program is not specific to the U310BT, so make sure you go to menu, select hardware, and select the U310BT in the menu.

You mentioned you loaded TTS files? what TTS files you loaded? Do you any better ones you can share with us?

Thanks

I'm come across the same issue on my U310BT. I tried a couple of different SD cards just in case one was faulty, but keep getting the same result. The cards work because I tested them by transferring other info onto them from my PC so I know they aren't the issue.

Here's a step by step description of the procedure I've followed just in case I'm doing something wrong. I'd appreciate any helpful suggestions as to what might solve this issue.

- I've installed Avid Feeds v2.1.1 on my computer.
- Formatted my SD card Fat32
- Inserted the SD Card into the AVIC face plate
- Connected it via USB to my computer
- Started AVIC Feed
- Selected U310BT from the hardware list
- Selected "Applications" from the menu
and all I get is a dialog box telling me:

Could not confirm device number of navigation device.
Insert SD card into navigation device, and connect navigation device to PC using USB Cable
