here in argentina the speed limit is 130Km/h about 80Mp/h.
but hopefully, here we dont have any kind of police control for speed ticket.. for you to know, i have jus tmade a trip from bariloche to buenos aires about 1600Km and almost all the time, the cruise speed was around 180Km/h 112Mp/h and i hit 220km/h 137Mp/h. everybody goes fast here, no ticket problems
but talking about the compass, tomorrow i will try to push it to its limit in the road and see the limit. maybe there is a problem or old software in my CVT or Engine, i dont know, i will get it for a starscan on tuesday or wednesday.
