I can give you a light recommendation for the Kenwood DMX709S

Light recommendation. I've only owned this thing for 2 weeks. I've driven it for about 60 seconds. But I have fiddled with the radio a fair bit in the garage. The things pretty cool really. Sound is pretty good, I believe he actually wired it correctly, which is commendable. There's a little microphone up on top of the a pillar I could probably do without. Fitment in the dash looks really good, in a way it almost looks like it belongs in the car. My preference would still just be the OEM unit, but I'm kind of stoked on this thing actually. The seller just put this in a couple months ago, so I would slightly guess that he did exactly this research and went with that unit. No camera or anything and I don't know what DSP is so I can't help you there.
