For the most part
1 - Custom gadz module
2 - LCD screen
3 - enclousure
4 - Video output for phone
1 - So you need customgadz controller (which controls your phone through bluetooth) Let them know what screen you ended up getting before buying
2 -Screen you can actually use an after market 7 inch screen like a pioneer or kenwood double din the only catch you would have to open up the unit to connect the customgadz controller to the pioneer touch screen. or you go get something like this

Whats nice with that screen is it has a wire that you hook up to your reverse lights and it will switch the unit to video input 2 which can be your back up camera and then when you put the car back in drive it switches back to video input one which is your phone.
3- If you go ebay route depending on year of car if you have a 2002 and below its a little more trickier since its a din and 1/2 and not double din you will have to do some modification. If its a 2003 and above then you can get something like this

4- Depending on phone you will need to output the video from phone to car lcd. So you can get something like this

which works good on some phone but others have problems cause they wont charge as you use it. So i ended up getting this.

which is nice cause it allows me to wirelessly mirroe my phone and charge it too if needs be Also there are so many options that you would just have research what works best with your phone and price. I got that unit cause it seems to work with almost all andriods, and you can get that unit cheaper if you search.
Hope that help. Ill try to get video tonight to show the unit in action and then when i get time ill pull it out to show the internal workings.
