So I have two requirements for the Head Unit I'm looking to get for my box.

1) It needs to be able to play MP3 off of DVD media

and

2) The *random* play for MP3 needs to be able to random on the WHOLE DISK,
not just the folder it's in.

You guys with DVD/Navi can you tell me which ones cover these needs?
I've found too many units that don't, and too many salespeople that are confused
by two simple questions.

 

The JVC KD-AVX1 meets your requirements. $436.94 including shipping from eCost.com.

Only bad thing is that you can't watch DVDs while you're moving, and you have to wire the HU to your parking brake to enforce this.

But it meets your criteria.
