I've been thinking about switching my head unit to an alpine. I currently have the tiny touch screen that ram provides on the express 2014 ram... it sucks... takes forever to load on start up like my music, back up camera etc.. so I've been wondering if I can switch to like a really nice alpine or Pioneer. I noticed on the touch screen options I can set timing for my lights, if my horn goes off when I lock the doors and other neat features... so what we're to happen to that if I switch the head unit? If it's even possible... best buy told me it wasn't possible.
