HEAD UNIT FOR W221
 

Good day.
I had a SMARTY Trend head unit installed in my 221 Mercedes a few months ago.
I haven't found many reviews, but there is information from various people on various forums. I want to share my experience.
I contacted them and decided to find out how it works and if they can ship to the US.
There were a few questions about the device itself.
UNIT WINCH I USED
I don't have AUX but have an NTG 5.0 system. The sound is through a special adapter that was included!
The technical support specialist explained to me all the nuances of my car and helped me to choose a really good quality device.
I am satisfied with it and paid via PayPal. The delivery was fast and took about 11 days.
