Yep, thats the one. It just plugs in the lighter/power socket and the antenna comes with windscreen suckers so you can run it behind the glovebox and up the a-pillar.
I didn't want to do that and rarely have back seat passengers so just ran the aerial lead along the centre console and up the back of the passenger seat. I've looped the top of the antenna in a knot around the headrest supports. You can't really see it and it works just fine that way.
There are some other more professional ones that you can hardwire in and plug into the aux-in of the stereo but they're a bit more pricey and a bit more of a faff. It's worth giving the V-DAB+ a go to at least see if you get a decent signal in your area. Buy it from Amazon and then you can always return it if you find there isn't much coverage in your area.
