Hi, i've got 3 kids and want to install a incar dvd system, without losing out on listening to music in the front, i want to know about the following: 1. How hard is it to install roof monitor (WOW quoted about $300, for that much i'd rather spenda few hours on it myself, i've done all my other cd players and even a auto elec mate said he was impressed with the install). Would it run off dvd headunit power or need its own? Where does it screw into? 2. Would 2 decks fit ok in double din slot? (DVD player for monitor and CD/MP3 for us in front? 3. would a deck fit in centre console pocket under vents if it was removed, or would i be better mounting dvd in glove box? if it won't fit in din slot? Any help would be good, i post pics and any probs i encounter for all who are considering same.
