I'm wondering if anyone has cracked the code on getting the system to index songs more quickly. Generally I'm running off bluetooth from my phone, but if I get into an area with bad connectivity, I'd like to switch to USB. I have approximately 80gb of music, and when I switch, it will take an inordinately long amount of time to index the music, and then it will want to do that every time the bike starts up. In addition, when you're indexing, you can't switch off it, and the only way to stop it is to remove the USB drive. Any suggestions are appreciated!
