Yeah, i hear that. I have been standardizing my base system with SBC's and mini ITX, which i can do other projects with when its out dated. The LCD...yeah...its aggravating to upgrade. I really wanted to just get it right the first time and swap out systems as my car progresses, with the only upgrades being new modules i add.
BTW, if you want to sell...

. i'll see what my funds say.
