Well it's not like Dynavin or Enco are big name brands... The things that would concern me would be that this could just be a lateral move and if you want navigation you have to add an additional module. And that's gonna be an issue because from what I've seen in my 330i, there isn't a whole lot of free space under the dash. At one point I was considering this type of unit, but with the screen out your access to the A/C controls looks like it would be obstructed.
Just my two cents...
