I have a front and rear unit in my 1st gen! It was great at first but then it just went to **** and stopped working! Don't know what the problem is with it, I always tried to format the sd card once a week! idk!
A lot of truckers use them because they have all those dipshits on the road brake checking them to try to defraud the insurance! Now that's smarts! Lmao! Wonder how many of those boneheads get crushed by 80,000+ pounds when doing that!
