to ronS & VBLUE:
to this point i have taken ronS's advice and deactivated the VR cataloging & i have not yet experienced the unit shutting off and rebooting itself as normal during that process (thanks ronS). both the ipod and nav are running simultaneously and i have not had an issue. everyone seems to post a ruff estimate of how many songs thay have on their ipod, mine is past the 10,000 mark, might this be too many for the unit to catalog, is there a limit? p.s. to ron S...i have not yet reset/restarted the ipod as i am having my computer which has itunes installed repaired.
I was wondering what happens if it runs out of memory while indexing. There has to be some physical limit. 10,000 is a lot of songs. When I first got my 64GB ipod Touch, I loaded it up with all my songs. But I soon realized that so many albums and artists made the user interface difficult to use. So I cut it down a lot. I don't think I every loaded 10000, more like 5000.
So, when you get your computer back, you can try a smaller number and gradually increase. Believe me, you won't miss those 5000 songs.
BTW, I was looking at mine on the way to work the AM. I thought there was a way to force a catalog rebuild from scratch, but I couldn't figure out. The VR Catalog off and on buttons worked, but it didn't seem to reset and rebuild from scratch. The manual is a little fuzzy on how this works.
