SD Card / USB input not working — AVIC411 Forum Archive

Dear all,

just a bought an used F900BT (EW version).

the drive was sold as being in mint condition and seems fully functional apart from the fact it will not recognize any SD Card or USB pen.

I've tried several brands/capacities and formatting options but still the icons on the Input selection menu are greyed out.

The unit was delivered with the original 2007 Teleatlas maps and i'm looking to update this and recover, at least, USB functionality.

Could the drivers be broken? Since no SD card is recognized, i'm unable to run testmode and make a backup.

I was not able to find a similar problem in the forum... can anyone help out?

The unit has V.2.009000 firmware & V.01.000800 maps

Thanks!

Ok, an update:

Just entered Service Mode (didn't messed with it) and on top of Uboot menu i have this reference: Avic-F700_R15_0319 256MB

Does this means that the unit have been flashed with a F700 firmware? Can this be the cause of my problems with the SD Card / USB input?

No, I believe the software is the same for 700 and 900s. They all report as 700s. (I am fairly sure on this, but not %100)

Thank you Pioneer4x4, since yesterday a new update:

i've tried an old 512MB USB drive and it works fine.

I also bought two new SD Cards to test (2GB Sony & Samsung) but the problem remains, i'm now almost certain that the SD input is broken and i cannot depend on it.

Is it possible to run testmode or do any update without the SD Card functionality? Can USB be used to backup and update the software version?

Thank you for the support

I think its the type of cards/thumb drives you are using. Firmware doesnt matter as mentioned above the 700-900-90 are all the same. yes you can use USB instead of SD.

Also, I was wondering, can you use a CD or DVD with the files on it? That would be a much cheaper way of keeping a permanent copy of them handy.

You try with an SD card with mp3 files in it?

If yous card is empty, don't enable SD icon on display. Try with mp3 or avi file.

Success!

Same issue here. After owning my unit for a few years the USB/SD reader just stopped. I know the USB and card work because they were previously in there working. Any help would be appreciated. Thanks
