My SXX is in the trash. I Didn't return it because I did so manny times.
In started with the SXX and chnaged to the GM. Now I have a Tekin and I am happy that I changed from speedo. Service is much better.
Updates were there before LRP came with it and my speedo's still run and i can't say that from my LRP. I have had 6 new SXX speedo's because the other speedo's stopted wrking in a race. Even power los after a few runs.
Autside that, the speedo was to slow.
My club members with a LRP switch from speedo as they must buy the V2.
Than all LRP drivers are gone.
Already some drivers changed to Tekin and GM. Some drivers will get the HW or the SP.
