yes, i'm planning to build a type c and i already have all the parts needed(only 1 sid at the moment) no problem if i have to buy some extra buttons, but for the din module, there's something that is not clear yet... shoul i buy an extra module or i can do everything with those 3 modules? it's about that "shifting 5 din pins" the din wiring on the pdf was not too clear for me, because from j15 of the core module and the display i have only 1 fat red line so...i'm just a beginner and from that schematic is a bit tough to understand how to "shift" plus: even my english is so so maybe if you can explain in another way i'll be able to do that modification sorry if i'm a bit retarded ::)but little by little i know that i can realize this project ;D thanx again for your help :)
