hi everyone, please bear with me, as i am a complete noob. lol i just installed my F90-bt and want to start modding it, in paticular the software bypass. i know i need to back up my files first. I ordered the 2.0 update from Pioneer , so they sent me an SD card with the update on it. my question is can that be my back up or shoud i follow the instruction on here and do it that way? i have no problem doing that but was just tryin to save a step.
