Hey guys, I was really bummed about not getting the RX8 navi...i felt like i did when i got the non turbo eclipse =(

but after seeing this https://www.rx8club.com/series-i-interior-audio-electronics-24/my-carputer-installation-54492/ from the great job MazdaManiac did, and RX8-XTC
https://www.rx8club.com/series-i-interior-audio-electronics-24/attempting-install-oem-navie-can-i-do-50286/ actually INSTALLING the oem navi unit into a non navied RX8
...
well, im sorta kinda maybe hopefull...
I want to install a carputer like MazdaManiac did but with the OEM look that rx8-xtc achieved...

so i need help, its not something i will be doing right away...i have a wedding to get ready for in july gotta scrap as much cash for it as possible...

so im thinking i need:
1. carputer (homemade or prebuilt
2.touch screen (what size can the 8 handle? 7-8 inch?

i want the screen to open up like the oem navi...but how will i do this?...do i need to get the oem dash part where the screen flips up? (sorry, im not tech savvy)
does the oem dash come with the motor+screen? extra cash on something i dont need...well...maybe the motor part

i need advice guys...help out a RX8 n00b
