Lots of info online. Am told that it was working well before being given to me. I was going to add it to my RV, but am selling that motorhome now.
Don't know much else about this unit, it appears to support navigation and TV tuner, etc.
Only comes with what is pictured, no harness. You can find one easily locally or online. I priced this with that in mind.
I expect typical high-end Alpine quality.
Thanx!
