can you get text display on both the obc and the nav display at the same time?

i seem to only get the nav display. the obc says cd 01-2 or whatever track i seem to be on instead of the mp3 song/author text.

also, is it normal to have ~1-2 sec pause between menu prompts as you navigate? if so, i suspect this is i-bus slow-as-a-sloth-sleepwalking-in-molasses bus speed?

in any case, i'm pretty happy with the ice-link plus! great product you got there Tom G! and i don't even drive the x5 or have an ipod! (both belongs to the wifey...)
