The KD-AVX2 has an internal dolby digital and DTS encoder for those interested int he movie decoding while the KD-AVX1 does not. It is very hard to find this fact confirmed on the internet anywhere about this unit but I can definitely say that it plays DVD dual layer. I burned the dual layer disc with Nero 7.2.3 in ISO mode, nothing fancy required. The KD-AVX2 has a 3.5" 16:9 widescreen LCD on the face, resumes mid-track when the car is restarted, and plays dual layer DVD+R for 8.5 gigs of MP3 per disc.

KD-AVX1 has some hiss between tracks which was not horrible but noticable, and was pretty slow in track to track navigation. The KD-AVX1 has a 3" 4:3 LCD on the faceplate, does not play dual layer DVDs, and restarts the track when the unit is restarted after you shut your car off. I have a JL audio A4300 amp with Focal TN52 front tweeers, Apine Type R front woofers, Focal rear deck speakers and a MTX 12" sub powered by the JL amp. I am not crazy overall about ipod audio quality. I do not watch movies in the car - there is a $80 portable dvd in the back for my daughter.

I became interested in these units due to the DVD-MP3 playback capability. Have not seen any posts here on these 2 units, of which I have owned both, thought I would give a post about them.
