upgrade firmware from SD card problems


Recommended Posts

I would suggest trying another SD Card or maybe trying to upgrade the firmware via USB1.  I have the 8100 and I upgraded the firmware using an SD Card and I had no issues.  My SD Card was 4GB and formatted to FAT32.  I also have the bypass enabled and parking brake grounded.

I just bought the 8100NEX and the first thing I did was upgrade the firmware from v1.01 to v1.03. (15MY_FW-Update_v1.03_16G_20150318.zip)

 

I used a SanDisk Ultra 64GB microSD card with the SD Adapter, formatted as FAT32.

 

I made the mistake the first time of extracting all the files/folders and put them into the root of the sd card.  Can't do that.  The files/folders have to reside in the AVIC5100NEX folder on the SD card.

 

But it took about 5 minutes to upgrade, and was successful.
