how exactly would i know if it was rescanning?
Honestly, I have no idea. I have the Navigation unit, I connected an external drive we use for back up and it powered it just fine, you could feel it reading the drive and the LED indicator showed the usual activity, but after 5 minutes I just gave up.
Then I read the owners manual and found this:
USB memory
l Compatible device
USB memory that can be used for MP3 and WMA playback.
Depending on the type of USB device, playback may not be possible.
l Compatible device formats
The following device formats can be used:
• USB communication formats: USB2.0 FS (12 mbps)
• File formats: FAT16/32 (Windows)
• Correspondence class: Mass storage class
MP3 and WMA files written in any format other than those listed above
may not play correctly, and their file names and folder names may not
be displayed correctly.
Items related to standards and limitations are as follows:
• Maximum directory hierarchy: 8 levels
• Maximum number of folder in device: 999 (including the root)
• Maximum number of files in device: 65025
• Maximum number of files per folder: 255
l MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1/10 of their original size using
MP3 compression.
WMA (Windows MediaTM Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3
format.
There is a limit to the MP3 and WMA file standards that can be used and to
the media/formats on which the files are recorded.

MP3 and WMA playback
When a device containing MP3 or WMA files is plugged, all files in the
USB memory device are first checked. Once the file check is finished, the
first MP3 or WMA file is played. To make the file check finish more quickly,
we recommend you do not write in any files other than MP3 or WMA files
or create any unnecessary folders.
The .pdf file was too big to attach, so here is the audio system portion (takes a few seconds to load) and the relevant portion begins on page 36 of the PDF (or pg. 348 of the paper version) and continues to page 42 (or pg. 354).
