Having spent a few days adjusting the position of the GPS unit I think that perhaps a higher grade option could be a nice thing to offer. I have a tracker on my bike that has a GPS unit smaller than the Innovv one and it get's a great signal even under the fairing whilst the Innovv one will not connect unless it's fully out in the open.
Maybe you could develop a universal GPS that could connect to several devices?
We have been working on the upgrading, add GPS tracking system to the K2.
