I am considering Carloop I an new to this product. I am curious to the function of the GPS mod. I have a 2005 F250 with intermittent rough idle and misfire issues It pops up codes but I need a running diagnostic device so in short I am looking for a tool that I can monitor all systems in my truck. Retail scanners that perform all of these tasks are way over priced and can be limited in specific function without paying for options you don’t need.
