my friend just bought a 2009 toyota highlander, and have jbl audio system in his car. he brag that jbl is father off bose and sound better. he compare his car to a 2009 nissan murano which carry bose. i'm younger than him so i don't want to argue with him in front of the group, and i can't prove that right. it just get me *BLEEP* cause i have bose system in my sedan!! so what do you guy think? anyway i looking forward to buy a gs350. i know that the navigation package come with mark levingson audio system with it. wondering if it would be better than bose, AND JBL?
