Can you give us a little detail on the Alpine Unit? I've seen it pop up online here and there and advertised in the dealerships but haven't read any real review of it.
Yup, the head unit is the 009 model, RAM Restyle. I am still learning my way through it so forgive my overly simplistic opinion of the head unit.
What I don't like:
It needs some type of anti glare coating or screen protector, for some reason it catches the glare from the sun and at times is almost imposable to read.
I need to set up the "short cuts" on the main screen, some of the options are not completely intuitive and you have to go searching for them (like stop route in Navigation, its about a 3 step process to get to it)
Its very expensive.
You have to cut the dash plastic and the inner support structure to install the head unit.
What it does that I do like:
SIRIS sat. radio
Navigation (very good, but you can't import FunTrek maps)
The head unit communicates with the truck and you can set up the Vehicle info. page to display up to 6 diff. items from intake air temp to motor torque ( very cool). It will also control your cabin heat, seat heaters, AC, and what not... ( this option has a quick touch button as well.
It has a metric ton of options for importing info, music and media.
it has a quick touch button for 2 cameras, and it works even if you are driving, just push the button and wallllaaaa...
All in all, it works very well and is light years better than the standard stereo. I can not compare it to the factory premium sound and head unit though, I don't / didn't have one.
If you have a specific question let me know and I will gladly answer it.
