I was considering that one for when I chop in my other car.
It is missing some bits, like the USB box, TMC antenna (if you want it), remote and if it doesn't have a lilac plug with a black/red cables, then you'll need that to use the internal mic.
I had one for years, got quite tempramental after some time. The zenec website has updates, which are now a few years old. If you don't have the box, at least get a 1-2m USB extension cable. You need a 4-8GB USB stick for updating, the instructions are on a pdf on the download page.
Radio is not as good as OEM but good enough I found may need a dual fakra amplifier.
