Hello All,

i was asking this in the general forum and was told this is the spot. i did a search a while ago and came up with nothing.

My main question is who has replaced their HU, and did you find it worth while. I'm asking cause i'm debating upgrading my NAV firmware with newer maps, or just a rip and replace. i want to make sure that i'm not wasting my money to rip out the stock. thanks for all advice!
