The stereo works almost as expected, my only issue with it is that the Turn Signal and Seat belt alerts

One caveat regarding this stereo is be VERY CAREFUL who you buy this from

This head unit is exactly as advertised and works great as I installed on my 2007 Chevy Avalanche, perfect fit, easy install!

The build quality seems ok, perfect fit and looks much like a factory radio

Install was simple and just like advertised is plug and play, except for having to install GPS antenna

All jacks, connectors, CANBUS just everything seems to work as it’s supposed to

I would recommend to anyone looking for a touch screen radio that looks like it came factory.

Easy installation, works perfectly, loaded up Sygic mapping and it all works perfectly

there either would have givin it 5stars if it wasnt for poor installation instructions

Easy installation, works perfectly, loaded up Sygic mapping and it all works perfectly

Installation was fairly easy since it came with factory plug wiring

All jacks, connectors, CANBUS just everything seems to work as it’s supposed to

Later read in a thread that the internal and external mic are connected together which causes poor mic quality.

It is much better quality than all the other aftermarket look alikes

All jacks, connectors, CANBUS just everything seems to work as it’s supposed to

Functions like it should, sound quality is way better than stock and the amount of options is awesome

It also connects via Bluetooth to my phone for hands free calls, with perfect quality

Also, the gps antina input port wire does not work with the car's antena wire

Everything else works flawlessly on this unit, GPS included.

I did have to buy two things, a ground loop filter found here on Amazon as well as a GPS

Add a mapping software to an available mini SD card slot and You get an amazing GPS system

Do to the angle of the display during the day the sun light affect the visibility of the radio, other than that it's a great product.

This is a nice looking product with lots of potential but has a very annoying electric whine from a ground loop issue somewhere in its wiring

Eonon GA8180 is by far the best product on the market for my Chevy Impala.

Shipment was fast, but the product is terrible

Volume for Bluetooth, AUX, and phone screen mirroring is not as loud as the fm radio, after listening on Bluetooth and then switching to radio I get

The radio sounds great and very customizable and it looks great matches my dash like factory unit.

Compared to what was in there, this radio sounds amazing and adds bluetooth and better navigation choices over the stock unit for much less than most other options

All jacks, connectors, CANBUS just everything seems to work as it’s supposed to

This radio had me really excited with the amount of features and value

The install shop did not like the unit because it did so much more than theirs and cost so much less

Unit defective upon arrival sound keeps going out will not buy from company again.

Wish I would of spent a little more on a better quality head unit

Also it doesn't have the sound quality the that stock or a more powerful aftermarket head unit provides

This unit was well worth the price compared to other branded units

no good no sound, radio looks to be working just nothing

I bought this to replace a nav radio that was starting to act funny (sound would cut out for a second and when it came back it sounded like someone changed an eq setting, also cds played with some static) in a 2009 Avalanche with the Bose system.

I did discover that there is a "loudness" button in the amplifier that must be turned on for the sound to be good.

The other thing that was a little surprising was that the sound was not great.

I have tried radio, CD, and BluTooth, the sound is fine, no issues at all

Only thing I was disappointed about was that the GPS card slot should of been a sim card slot.

Since GM does stupid things like making the door chimes and turn signal sounds play through the radio this also comes with an interface and separate speaker to play these sounds...except they sound HORRIBLE

I will provide more info soon but this thing is amazing!

I'm sure somebody will devise a way to fix this as it seems like an easy thing to remedy.

The only issues I have are, the annoying speaker that it comes with for the door chime ect

To hear your blinkers and door chimes and such, you must use the supplied speaker, I suggest cover all holes except one to tone it down because it is a cheap loud speaker

The speaker that provides the turn signal and chime sounds just sucks

The speaker is obnoxiously loud for turn signal sound and seatbelt reminder

Everything hooked up, funny looking thing like a speaker NEEDS to be hooked

And it lags all the time

Cons: it freezes all the time and i have to constantly reset it

Only reason I am giving it 3 is because it is a bit slow and has a hard time processing things
