Summary: Despite the ratings above, I like the sound quality of most Eclipse headunits. The Eclipse AVN6620 is not a bad unit for what you would pay now. Eclipse took emphasis off the audio quality in exchange for navigation. Eclipse is no longer making after market products, so you may not be able to get one of these anyway. Navigation is not bad, but not great. Also note that bluetooth is not built into the unit. You have to get the Eclipse version of the Parrott bluetooth.
