Is the LEX89VL2 compatible with the 2014 LS 460 with nav? When I look up the VL2 product page, it only says 2015 and up which doesn't seem right given 2014 was the start of a new generation. If I search for a compatible model with the vehicle search, it pulls up the LEX78VL2 which apparently is also compatible with the 2014 IS 350. Are these VL2 models interchangable between these vehicles?
