Car Stereos: In dash video, double din head unit, factory radio


Question
I was actually wondering if i was able to put a 5.8 touch screen video in my 2004 chevy impala?

Answer
Hi Trisha,

There's no reason why not.  The dash opening is large enough to accommodate a "double-DIN" video unit, although you'll want to use a mounting kit to install it.  You can also install a single-DIN, "flip-out" system with a motorized screen, but the dash overhang in the Impala makes that impractical with many models.

The challenge with many newer GM vehicles is that the factory radio is integrated with the vehicle's data bus system.  When you remove the factory radio, you'll lose some vehicle functions.  The most noticeable difference will be the warning chimes: lights left on, door chime, headlight chime, seat belt reminders.  All these are generated by the factory radio.  If you have Onstar, that's another system that requires the factory radio to operate.  

You can purchase after-market adapters that will keep your warning chimes and Onstar working.  They're fairly expensive, but they make the installation much easier and keep the new system working similarly to your factory system.

If your factory audio system is the premium Bose package, you'll need the GMOS-04.

If you don't have Bose, but do have Onstar, you'll need the GMOS-01.

If you don't have Bose or Onstar (or don't want to keep Onstar working) you can use the GMOS-01 or the GMRC-01, which may be a bit cheaper.

All these parts are made by Metra, and they're available from many online vendors or local car audio stores.

In addition to the interface adapter, you'll need an antenna adapter: part number 40-GM10.

The mounting kit you need is the 99-2003.  It includes the kits for a single-DIN or double-DIN head unit installation.

I hope this helps!
