Has some few issues, but still it's the best option for someone who wants to keep original audio. + sound quality, + USB music, + mic and remote control included, + works as handsfree - needs some work to install

29 May 2019

Perfect packaging, contains everything it says, very fast shipping, i don't install it yet but happy with the purchase

24 May 2019

So far so good, just hooked it up. It’s a cheap and easy way to bolster the functionality of the OEM stereo.

23 May 2019

Works wonderfully! Hard to install since there is a black ”fuse” box (contains a fuse and circuit board) near the end that connects to the back of the radio, and it’s too big to fit through an importsnt hole in the dash. A tip is to remove the box and then route the cable up to the radio and then reattach the box.

13 May 2019

All so as you need work. The fact that troszeczkę need to pobawić with kabelkami where rozmieścić, but phone wireless Bluetooth works purely unlike transmiterów FM and I checked their already some and it with top shelf. Also as Mat Mazdę 3 it recommend this product and no what the play in półśrodki..
