Oh, and I got some more $1 parts 3 mobile holders. These are for the V60, but with a little creative modifying, they fit the larger V505.
Hands-free speaker and mic location
Phone holder installed
Holds up to high-G turns quite well, sounds great, works great. Very convenient for a total investment of $2 (installed parts). I actually spent about $7 total, to have extra stuff to play around with to make it work.
