Mustang V.

Ordered GM5164
Delivery
Arrived after 10 days, while i paid for expediated shipping 3-5 days.
Tracking system showed it traveled halfway around the world before reaching.

Packaged beautifully, the main carton was suprisingly tiny and had few tears, but intenral boxes were strong and okay.

Product. Product quality is Grade A,
Price is very good, it could have been a lil bit more cheaper though

Problems, yes there are few issues,
The Gm series are the ones with Miracast feature, something no other brand or non brand has ever attained, with that said, I could only use the miracast feature just once perfectly, their software needs fixing and they dont even admit it.

I bought my product with Tpms and the Gui of the indash needs tweaking to properly work with tpms.
After sending about 10 emails explaining to them that the tpms is at times acting $#*!y, they finally say okay send tpms back by shipping and we will test it and if its defective we will send new one, I BEEN TRYING to tell em that the Software of indash needs tweaking to properly work with TPMS not TPMS is defective sheesh.

Sound quality is Goos, it could have been awesome. The problem here is the 2 subwoofer outputs they have in their inbuilt amplifier,
My full option camry has great speakers with inbuilt woofers, but i dont have any subwoofers. Now i after paying for an upgrade am stuck with an amplifier that is sending flat signals to my speakers, because it relies on 2 subwoofers to give bass. This is ridiculously funny. But hey the quality is good, just flat bass :( I will not add subwoofers to my car, knowing my speakers used to handle bass extremely well on the original amplifier.

After Sales service, is okay. They are frienmdly, but hey my issue was not solved, and i just let it slide, knowing that i am happy i didnt get scammed. The products are good, But buying a D series is better option than GM series, as its eaven cheaper and it has all the features u will be USING on THE GM series lol.
