Hello, I'm new to this and would really appreciate some help. I have already updated my firmware on my F90BT from pioneer but i need to update my maps. Since I haven't done this before, I've been reading some of the post and I have downloaded the torrent file. Do I also need the hacked ezrider? Also how do I back up my unit so if my update goes wrong I can go back? Thank you all in advance for your help.
