You can buy a similar name brand head unit at the big box electronics store for 400 bucks or more, or you can pay sub 100 for this one. Which one you choose depends on your needs/budget. For me, I was replacing a stock radio/cd player in a 2007 truck. It made no sense for me to spend 400 PLUS installation for an almost 20 year old vehicle. WORD OF CAUTION- Before you buy any head unit from anywhere, do your research on your vehicle to find out what you need for installation. In my case, I was going to do the install myself, after all, I did a half dozen or so in my youth. Vehicle wiring has changed a bunch over the last 20 years so first off, find out how much a wiring harness will cost to convert your system to the new unit. The wiring harness needed for my vehicle was almost 100 bucks. Also it was not as simple as splicing the wires together to save money, the speaker ohms were different and there were a ton of assorted wires running through the radio that I could not decipher even with a schematic. I ended up paying an installer another 179 to put it in. Still, my cost was a lot lower than had I purchased the 400 system from the store, and you still have to purchase the wiring harness and conversion kit even if you get a free install.So, the cons of this system from my perspective...I wanted to use this for navigation but I did not read the fine print on the listing for which versions of android it supports, mine is 11 and I own a Google Pixel, which does NOT support Mirror Link, therefore, I can not use navigation. So while I don't hold the seller accountable for my oversight, I strongly recommend that you understand what Mirror Link before you purchase this unit, especially if you want navigation on your screen. Android Auto and Mirror Link are 2 different things so know what you are buying!Upon starting up, you get a Welcome screen and it takes a few seconds to begin playing music. It takes a second or 2 longer than my new VW screen so not too bad.I have read reviews on other units of this price range and it appears that it may only perform one function at a time, kind of like your TV when you switch inputs, the show you are watching disappears and it pulls up the new input. So if I am listening to music from my usb card and I press the AV input, the music stops. When I loaded my phone contacts, music stopped for 20 seconds while my contacts loaded. Truly not a big deal for me, but fair warning in case it would be for you.The steering wheel mounted controller is convenient, however, the connector attaching it to the wheel is velcro fabric so when you press a button the controller moves easily...so you have to support the back of the controller when pressing buttons, and if you apply too much force, the controller will pop out of the housing, It would be nice if it had a locking feature as I have popped it out of the housing and onto the floor a few times. Maybe I can rig it so it is more sturdy as I truly like it. It also does not work well unless it is closest to the radio. When I had my wheel cut far to the left I could not change the music until the wheel rotated back close to the radio.The biggest con for me is there is no folder option to scroll to the song you want to listen to. You can only go forward or back one song at a time. (You can shuffle also). I miss being able to pull up my library, but if you have a smartphone and connect via bluetooth, you can simply tell Hey Google or Hey Siri to play what you want to hear.Pros- UI is intuitive. I have not had to read the directions to do everything I have wanted to do so far.Bluetooth connected easily and seems to function well.Phone works well through bluetooth, I have taken a couple of calls and it works as well as my VW system. I assume there is a built in mic on the unit as callers hear me well. I loaded my contacts in about 20 seconds. I played music through bluetooth and it worked great. With my smartphone, I just tell it what I want to hear and it plays it. Also was able to voice command my phone to make phone calls so the unit is truly as hands free and my new car.You can play videos on the screen provided you have them saved to a USB, (and I believe it also has a TF slot). The USB works well and its pretty fast starting up.The display is good, not as sharp as my cellphone but plenty good for a dash unit. Color is good and it is plenty bright. The attached pictures were taken at noon so it was bright outside, and I still can adjust the brightness up if needed.The bezel color can be changed to 8 different colors, one being a multi function that scrolls through 7 of the colors every few seconds.There are 8 wallpapers, but they are all really subtle and on a dark background so I dont even notice them as the interface is your focal point. I dont see an option to add your own wallpaper but no biggie.There is a basic EQ and also 6 or so presets for Rock, Jazz, etc.The steering wheel controller is really convenient.It has a camera and a handheld remote but I have not used either either of these.It switches from bluetooth to USB to radio very quickly, no lag time.My favorite thing about this unit is the sound. I was shocked at how much better my music sounds. I had previously been listening to music via a 3.5 cable from my phone and the difference in sound with the new unit is astounding. My 14 year old speakers sound brand new.All in all, I am extremely happy with this head unit. In summary, if your phone allows Mirror Link, and you dont mind a few quirks, this is a solid buy for the money. As long as you are not expecting it to perform like a 800 dollar Kenwood, this could be the one for you. Just to avoid any disappointment, if you want the traditional Android Auto experience, spend a little more and get it, otherwise, this is an incredible upgrade from my stock unit!
