Question: Does this head unit have a removable face? And does the screen go back into the head unit when you turn it off?  Wondering about theft prevention.
Document: This is by far the best head unit for the price! I wanted something with video playing capability along with navigation. The higher end units you had to purchase the navigation separately, generally the navigation accessory was the same price as this and the head units would be an additional 300 to 500 more. This unit has lots of great options!. I have a van with a video screen in the back. I have this hooked up to it so the kids can watch movies on long trips.
This applies to the LCD on the face of the unit as well as the screen.
I purchased this to replace a very old &#34;brand K&#34; aftermarket head unit that was overly complicated and lacking in features.Installation was straightforward, but anyone who hasn't installed a head unit before should take note that the only instruction provided is a simple wiring diagram.
Loaded a bunch of music videos onto a mini flash drive and plugged into the USB cable out the back of unit. The cable for the USB and Iphone/pod I ran into my glove box. So they are out of the way. Could do the same with digital copy movies. I put movies onto a 32 GB mini SD card. The back up camera is a nice feature as well. this unit has it all.
Installation recommendation, connect the 12 volt trigger to a switch, NOT the backup lamps. In my unit, the screen opens and retracts each time the car is placed in reverse. If you're a bad parallel parker like me, the screen will be going up and down several times each time you park.
Bought this unit for a long drive last Thanksgiving. It delivered and everything worked including navigation. The only thing I haven't installed is a rearview camera which I plan to add for our trip during Christmas. Sound quality was acceptable although not as good as my other brand on another car and I wished the clock displayed even when the pop out screen is off but there's no way around it.
Radio works great like all the features,,, GPS is very accurate  ...detachable face...I'm happy with it  ...also good price...will recommend to anybody
Radio display when screen is open is particularly good looking.Seems to have plenty of undistorted audio power.No problems with the operation of the touch screen.
Quality stereo. Has touchscreen and Bluetooth enabled and is very easy to use. Love the built in GPS. GPS is independent and does not require your phone or other device to work - goes through the stereo alone. Like that music will play with the GPs on screen. And this programs easy to my steering wheel controls. I suggest starting with 1st control on wheel and then the next in order. Then follow up with assigning stereo keys that match, Easier.
Maps that come with the unit appear to be fairly up to date in my area (Chicago).
Answer: Yes it has a removable face, and the screen does go back into the unit when you turn it off you can also retract the screen without turning the unit off if you want.
