What are these?

 

I am surfing throughout the file structure trying to find the root of some of my glitches and I stumble accross files that say "Device.nng"

What are these and are they necessary?

Thanx,

Bud

The Device.nng contains the Serial Number of your device and is i.e. needed to sync with the Poicon Speedcam Service. Take a kook on you SD card, it is copied automatically onto every SD Card you use in the unit

I just put f700bt in my car and was playing around with the sd card.

My unit came with 2.000 version and when I use my 8gb microSD in the SD adapter pluged into SD slot on the front of the avic it works fine, reads music and video ok.

When I remove it and plug it into my usb2.0 dongle and plug it into USB cable, dongle will flash and flash but nothing happens and USB is greyed out on the source menu. It looks like there is nothing pluged into usb cable.

 

When I check the sd card on my pc it is blank except for the device.nng file.

I think it is a glitch or my usb dongle is not compatible 100%.

 

Did anybody else had this happend? Or it is a good excuse to upgrade to 3.0?

 

Let me know - before I plug in my usb flash drive and loose all by data on that too

Thanks.

 

Had 700bt for 2 days now and love it and finding avic411 I love it even more - Thanks all you guys it is great forum.
