Thought I'd throw a quick update in here.
I got the Xtand eventually.
I originally ordered from the link posted up but they didn't have any in stock. I waited nearly a month and eventually got fed up. To their credit, they did keep me informed of their progress and refunded without any hassle but I found one cheaper on Amazon and bought that.
First impressions...cracking bit of kit!!Well made, has fittings for iphone 4 & 5 included and is well designed.
Unfortunately my car has been off the road for a few weeks so I haven't really had much of a chance to test it. Rear brakes were seized so I have replaced discs and pads and my front shocks (which have been on their way out for a while are now in desperate need of a rebuild. I am away with work on Friday so the GTV is going into the garage and work will resume when I get back.
I'll post some vids when we're going again!!
