Just had the 8200nex installed in my 2016 jeep wrangler. Had it done at best buy with maestro and everything is working except that I have no sound when Im using the navigation. Doesn't matter what app I use or if I use the head unit's navigation. Wondering if this is a hardware issue or if the installer maybe didn't hook it up right. Or maybe it is something silly that I don't know to look at it. Has anyone had this issue? Ive tried everything. Searched this site and google and can't find anything. Any help would be appreciated. Thanks!
