Might wanna do some research on that Dual brand.
There might be a reason that it is priced that low.
Ive seen comparable systems from brands like Pioneer, Alpine, and Kenwood go for $1400+ with the same features.
I would be careful since it seems the common problems on these are motors and touchscreen not workin like they should.
If you do go for the in dash unit, might want to look into getting the the extended service plan just in case. I think the max would be 3 years.
