Help! Replacing an 01 GM radio with aftermarket flip out tv! Need kit????

I have a 2001 chevrolet venture wb edition minivan. I have on star and an RDS radio... What will I need to swap the radios??? I have the GMOS-1 adapter for on star but it says it doesn't work with RDS... Helpppp!!!!

the adapter should work you will just not retain the rds function that is built into the factory radio and the rds is broadcast by the stations that is why some stations have info and others don't. Hope this helps.
