So Im contemplating wasting some more cash! Been thinking about upgrading the radio for a while and a new touchscreen would bee sweet. Im kinda on a budget but I was looking at something thats touch screen interfaces with my Ipod and has blue tooth and I found this

Boss BV9155B In-Dash 4.5" Monitor with DVD/CD/MP3 Player

Idk if anyone has any experience. Also what would I have to buy to use the steering wheel controls still? Any advice thanks
