Great price for an android radio. Has so many features that eveyone will use. I can not only listen to music, but do so many things such as run android apps, and since i have a sports car, run Torque app to monitor my car's engine functions.
Waiting for backup camera which was a nice add on feature at no cost due to the promo when I bought it

Bought this head unit and followed instructions on YouTube to replace the stock unit with this and it turned out great. I've never replaced a radio in a car or anything, but they mad it pretty easy and it looks and sounds great. Love all of the functions and it does everything described in the details plus I found more things it could do. I would totally recommend this to anyone. The only slight difference I found in the sound is that it doesn't seem to be quite as loud as the stock unit could go, however it isn't a significant difference. It still gets pretty loud when jamming out in the car.

Okay the radio it's self if put together very well and the android operating system is a plus but when it comes to actual Audio it sucks. My stock Mazda head unit played better honestly. For this price you should get really powerful sound not just an android tablet as a head unit. I thought the sound would be better.
Pros:
-very nice build quality
-good operating system
Cons:
-audio quality isn't good at all. Stock head unit has more power and I dint even have the bose one.

Buttons stopped working 3 days after installing it

Will update when new unit gets here
Go through the Amazon seller for warranty

Well almost a month after USPS lost my package, the new unit is here and it is faster and much more tactile, also came with the mounting plates to make it sit flush...pretty sure I got a defunct unit last time around.

Store worked with me until I got the final product that I wanted :)

Vehicle 2010 Mazda 3s

Pros:
"¢ Very easy to install, no soldering required, all the required adapters are included. The hardest part is dressing the GPS and microphone cables.
"¢ No programming of steering wheel buttons required. (only volume, skip back/forward and source input selection are supported.)
"¢ Decent FM tuner, seems better than most in this category.
"¢ Boots up quickly after the initial hard boot of the Android OS.
"¢ Fit and finish is excellent.
"¢ Will support a 64GByte micro SD card (32GByte is advertised)
"¢ Large icons, easy to see and touch while driving
"¢ Very responsive
"¢ Simple interface layout
"¢ Spotify works (Make sure you have a reliable SD card for the Spotify cache, else you will have problems loading Spotify. Also, you may have to reverse the forward/reverse steering wheels controls in factory settings)

Cons:
"¢ User guide, I have a Bose system, the manual does not mention how to install the head unit with a Bose system. The user guide also talks about an external WiFi antenna which is not included.
"¢ Bose adapter/filter is poorly designed, the plastic housing appears to be crimping the wires exiting the filter, I wrapped the wires in a layer of electrical tape for extra protection and cut away part of the plastic housing.
"¢ Marginal to poor WiFi strength, keeps dropping when connected to my home router which is only 30 feet away (I operate devices beyond that range with no issues). I believe this has something to do with the really small WiFi antenna on the unit. When using a smartphone with hotspot enabled in the car this is a non-issue.
"¢ Microphone is a bit bulky to be mounted on the A pillar, it's in the way when I move the sun visor.
"¢ No steering wheel support for making and receiving calls (no big deal for me, screen buttons are good enough).
"¢ Support staff tries to help, but they are not very good.
"¢ Need more options to customize volume controls. For example, the ringer volume is very loud, but I cannot reduce the ringer volume without reducing the overall volume level.

Overall:
I'm satisfied with the purchase; my initial purchase was directly from Eonon ($50 less than Amazon at the time) but the unit they sent was defective (generated a lot of RF noise). After troubleshooting with Eonon I got no where and requested a refund, I was charged a $15 shipping fee. I then purchased the same unit from Amazon (better return policy) and there was no RF issue. Eonon needs to work on providing better documentation and support.
