Hey Everyone!\n\nI'm back in a Titan after a brief hiatus for a Subaru and I am loving my 2017 4x4 SV! I loved my 08 and this is one is a step above. I do have a couple questions though:\n\n1. I have the leather package and the dash is wrapped with a vinyl\/fake leather, what do you ya'll recommend as far as a product to keep it clean?\n\n2. My GPS voice all of a sudden went super low and I can't figure out how to turn it back up. I've searched far and wide and found nothing. If I missed something on the forum, I apologize.\n\n3. I don't have the Rockford system and want to upgrade the speakers and amp. Any recommendations?\n\nAnything else I need to know? \n\nThanks!
