I'm looking at a N810 since it has USB OTG, and I have a Canola question: If I have a large hard drive with about 30000 songs, will indexing/searching with Canola be quick? I would like to use it as a car MP3 player.

Also, while in the car, I would like to use the N810 as a GPS for navigation. Would there be any issues switching between Canola and GPS? Can one switch quickly from one to the other?

Thanks,
Folsom
