Hammerhead Karoo 2 – Images & New Interface

Here are a few ‘leaked’ images via GCN of the Karoo 2 which show a stylised, smaller format than the original Karoo. (GCN Video link)

‘New Look’ Interface

Here are some screen dumps from the new Karoo 2 interface. The ‘new’ screen looks nearly identical to the Karoo 1, in many cases, it just looks to me like the font is a bit bigger plus some minor screen flow changes and mapping tweaks. Have a look and see what you think, whatever the breadth and depth of the exact changes this is still a sweet-looking thing of biking beauty.

I’ve covered most of the important Karoo 1 firmware releases as they happened over the last couple of years, have a look below to see how some of the more material changes have progressed over time. It’s a series of impressive, incremental improvements.
