Noobie...So after a lot of reading I am thinking that this is the way to go to retro fit BMW apps to my 2012 e70 cic system, right? I currently have factory prof nav, with basic Bluetooth streaming, connected drive that shows BMW assist, BMW online but can't register on connected drive, says deactivated, and sirrius radio. What I'm not sure of is whether I should bother backing up any docs/fsc certs currently working before I run this to add the BMW apps fsc. I understand this patch tool will let me import all new personal fscs tied to my vin using fstool or ista (either one easier?)It seems that would post date and invalidate my factory certs right so why backup? After updating my own fsc I would have to generate the new map code as previous with the actual factory cert before nav will work after new cert import. Lastly have to add 6nr via coding to hu cic and cmb media with changed fa code. Think thats it. Is this worth it for BMW apps? Seems easy.
