lately when searching using my ipod touch videos or music my unit tends to block miss or can't find artist name alphabetically but its only blocking letters D through H says not found everything else I can search alphabetically . I put the same iPod touch in my truck with the 930 and it works fine

I have totally reset the unit disconnected from power and totally reset the iPod touch still the same.any ideas

I'm having the same issue with an iPhone 4 except it would not find artists A-Q, then recently it stopped finding any artists. Any letter i touch it says "Not Found"
