Yeah, GT is the resident expert on this topic..
I've been comparing the RHB
to the RHR
... according to the listed info on those pages, they are identical units (other than the nav). But I am no expert.. I just know what my truck currently has and need to know if the 430N RHB would be a plug and play application or if I would need additional parts or whatnot.
As for the seat belt chime.. no.. but I'm learning to just live with it..
