Just thought I'd post this up in case anyone was looking into fitting one of these units to their car.   I noticed the RCD330+ being mentioned on a couple of other forums, so decided to take the plunge. Purchased a NoName unit from AliExpress in early Jan, and have been running it since. Considering they only cost $150, it's a massive improvement over the Bolero!   I was previously using a Joying Android head unit, which cost a lot more and had considerably more bugs.
