HD Screen For BMW 3 4 Series（TAX FREE）

Everything you needed was in the box,Road top are always at hand if you need any advice and the kit is really good,cheaper than some others out there and easy to install.
I would highly recommend both Road top and the equipment.

Easy setup. Working very well. Fluid and powerful

I also reviewed this item on Amazon.

I’m very happy with the purchase. I was able to install it alone myself and I have no experience with cars or electronics. It is a beautiful touchscreen CarPlay system and looks like a thousand dollar upgrade if I brought it to an auto sound place.

I was thrilled to have done this myself for such a small expense. If I can install this anyone can. With their instructions and some patience getting all the settings correct it works perfectly and toggles back and forth between the OEM system seamlessly.

I have not had to do any updates to the OEM system to see if it syncs, but so far it’s amazing. Great purchase and arrived super fast by UPS.

Sono essenzialmente molto soddisfatto del prodotto, si integra a perfezione con l'auto e, pur presentando qualche lieve bug di tanto in tanto, funziona perfettamente, in modo rapido e senza lag. Il monitor ultra sottile è molto bello e ha una definizione eccellente. Ho collegato anche la retrocamera e va tutto molto bene. Secondo me l'unica pecca è la dimensione del monitor, avrei preferito un monitor da 10" ma ripeto è un mio parere personale che va al di la della recensione tecnica. Lo consiglio vivamente

The screen works straight. My only suggestions would be that the written instructions be better, but I figured it out.
