GMC Terrain...how to change speedometer from k/hr to k/hr
push your menu button down by the cd slot to switch to vehicle stuff- then clock the up or down arrows next to it until you reach the "US or Metric" choice- then press the set/clr button to change it, then press the menu button again to get back to the mileage etc. screens. I hope this helps.
A friend left a can of pop in my GMC terrain and it exploded and pop got all over my buttons for my AC and heat how do I clean them so they aren't sticky
