I recently purchased a 2008 ES 350 as a number 2 vehicle. It has the Mark levinson audio system and navigation. I am interested in upgrading both systems to today's abilities, primarily where the system will communicate more efficiently with my phone. I plan to purchase a system and have it installed by a reputable aftermarket shop here in Raleigh. I'm just curious if anyone has done this and what I might be getting into Thxs
