Audio Systems: Nissan Sentra CY068, nissan sentra, bose radio

Question
I need to replace the radio on a 2000 Nissan Sentra.  On the front panel it is marked CY068.  I can't find one of those but I can find CY290, CY330, and others that look identical.  The CY290 is from a 2002.  Any idea which part numbers are compatible with the CY068?  Thanks!!!

Answer
if you have bose  look for bose radios only
if you have the regular system you can not use the bose radio is that simple they all will work  they look the same in the back with the same plugs  

just look at the CDC button and the SAT button no other difference
