Hello everyone, in a few weeks I'll become a proud owner of a 2020 f48 x1. Since the car currently has a 6.5-inch basic system, the first upgrade I want to make is an aftermarket Android system. I've spent the past few days searching and watching videos of various models. My question is: are the systems sold by American retailers like Avin and many others actually better in quality compared to those found on AliExpress, or are they simply resold at inflated prices with additional post-purchase support? Because I'm hesitant to spend $800 on a system that might be the same as one I could buy directly on AliExpress for $400. Do you have any opinions or experiences on this?
