iPod 5.5gen - Page 4

Yes they are slightly different. The 5.5G has a search facility which the 5G does not. If you go into Settings/Main Menu after the Radio option should be Search if it's a 5.5G. All 80GB Classics are 5.5G. In the Settings/About the model number for a 5.5G is MA450LL. For a 5G it is PA146FB. There is a myth that the sound quality is inferior on the 5.5G, where this comes from I don't know. For me the 5.5G has very slightly improved sound quality via the firmware.
Slight correction, all iPod 5 or 5.5G comes with only 30GB or 60GB which are known as iPod Video while 80GB / 120GB / 160GB are known as iPod Classic from 6th Gen onward.
Myth or Legend, both are still using the same Wolfson DAC. Only difference is the Search option.
