A pair of audio/video inputs lets you connect a video game console or other video source. You also get a handy wireless remote and mounting gear.

The slot disc player works with most disc media formats, including rewritable DVDs and CDs, plus MP3 discs. You can plug a portable player into the USB input and enjoy audio and video media through the RM-921C. Or put a memory card loaded with compatible digital audio or video into the SD card slot, and enjoy the images and sounds on the go.

Please note: Overhead monitor installation is a complex and lengthy process — it is recommended for experienced installers only. If you wish, you can purchase a prepaid InstallCard and have a professional take care of the installation for you.

Great Value

Dennis from Jersey City, NJ on 11/7/2009

Crutchfield Customer Review (What's this?)

Outstanding product! The slim design flows well with my Nissan Quest's (2009) overhead. The unit is simple to use--my 5-year old son handles it (and the remote) with ease. The screen is large enough to easily view from the third row seats. Unit was professionally installed by a near-by (walking distance) authorized Received only compliments. The only downside is interference when using the sound thru the FM radio. (In the NYC area, every FM frequency seems occupied.) Overall great value.



Easy to install and it works great

kevincp from Rancho Cucamonga, CA on 10/22/2009

Crutchfield Customer Review (What's this?)

It was a pretty easy installation once I tracked down the wire I needed to tap into for the 12v after ACC power. The flip down lid on this was a bit tight at first, like a new laptop and didn't drop when I pushed the open button. It has since loosed up and works OK now. As for the functionality, it just worked. The FM transmitter (like any) is OK, but you hear hissing. At least this unit has the ability to directly connect it to my car radio (if your radio has that ability). I have to buy an adapter for my 2009 GMC Acadia. Overall, I would buy it again. The wireless headphones (FM frequency like as well), were OK, but they simply worked when I turned them on. No programming. The overall quality of this product is great and well worth it. Especially when you compare it to what the GMC dealer wanted for their DVD player. They wanted $1200... no way.

Bobby from Athens, TX on 6/10/2009

Needed a replacement for an older unit in Tahoe which didn't have built in DVD. This unit works great. Very simple to use w/ included remote. My 6 year old can operate it himself. Nice picture, good sound. Works w/ generic brand headphones. DVD slot next to front seat passenger so they can easily exchange DVD. Plays DVD R's just fine. Nice memory function. If you are playing a movie and turn off the car, when you restart the car, the unit comes back on and picks up where it left off, great for the kids. The unit feels solidly built. The only complaint I have is the overhead lights are led type and are a bluish white. They work fine and run cool, but don't match the other lights in the car.
