One of my client have this problem with his sip digital speedometer that I installed (part nr 50000710).
He wrote me this :
Along the waythe countergo crazyevery time.After agood twenty minutesdrive,it says199 km / hand then nothinglikespeed.TheneedleTourshasalso disappears going on the max.Just thetemperatureand timeremaining.The space ofkm / hbecomescompletely empty.And it's reallyevery time
I bought my speedo 2015, and installed it on my sprint. In end of last season i got the same problem as description earlier in this tread. I have tried to find a solution without success...
But now i found this, so I need a new blackbox. Do you replace the new or do I need to order one?
