just wondering if anyone with a SLE has tried to install a factory HUD from a SSEI? if so, how bad is it to do? mine is a 2005 SLE but i'd like the factory HUD for it. just wondering if it was something you could do without hacking the harness up or damaging the other car functions? would need the dash cover, the projector , the controller and? i know the window film too. hmmm.
