I gave up on mine in the end. It was a bit susceptible to inclement weather. I solved that by an inner tube until the seals went. They did send me a replacement and I think the new unit has better seals altogether. I was going to stick with it when the new seals arrived but I got good news about my job and it was a little erratic starting after a stop so I treated myself to a 4iiii. On reflection though the data it supplied was good relative to my 4iiii. I got a factory fit of the Avio though, I hear they can be a bit erratic after a DIY fit.
