Thread: Honda HU - Secondary root causing NG to hang

I'm not sure, that you are even know, what you want to have. Your HU has two USB slots, but I am pretty sure that there is also one sd card slot, for Navy only.
If there is no sd card slots, then let's talk about iGO...

You cannot have two folders named iGO on your device, one on internal and one on external... Thats why it doesn't starts.
Further, what does you try to have? Whole iGO folder on external, or iGO folder on internal and only secondary root with maps content on external?
Based on your screenshots, you try to get iGO working completely from external, but you don't have sys.txt in that iGO folder. And if you want that, you have to completely remove any iGO folder from internal, put everything in iGO on external, and you have to edit your apk file!
Your sys.txt probably doesn't have lines

[folders]
linked_root_list="/mnt/usbdrive2/"

because they are not standard. You have to add them in sys.txt, but problem is, that you have to add this lines in sys.txt that is packed in your apk file, so that installed iGO World knows where to find data folder.

So, I think that for you is easier to put iGO on internal, and on external create /addons/content/ and put there all map and poi folders.
Then you ad in your sys.txt
[folders]
has_secondary_root=1
android_secondary_root_path="/mnt/usbdrive2/addons"

Then it will works.
