Hi i have a mitsubishi lancer gts 2009, and it has the bluetooth handsfree system installed, I changed my cellphone firmware about 3 months ago so my phone wasn´t pared with my car, but today i wanted to pair it an then I discovered that when I press any button of the handsfree system panel at the steering wheel, it doesnt do anything, usually it says "HANDS FREE SYSTEM READY" but now it doesnt happens, but in teh nigt when i turn inner lights on, the panel buttons turns on as usually, could someone please help me? what should I do?
