Just got my gts and God im in love. Mine came with phone model and i use two sim cards for same number (duel). First my iphone 5 paired with the pcm but suddenly stopped pairing with an error indicating aux/bt connection which i searched and hopefully it will work now. However the pcm phone doesnt turn on sometimes and perfectly work other times. Is it a fault in the pcm? Is it fauly in the antena? Help please..
