Petey_370z_110BT

My 370z 40th anniversary edition's been totalled twice and only has 20k miles on it... (bought with salvage/recertified title) so what anyways most importantly it came with a Z110BT! has FW 1.000000 and came with bypassed e-brake, I presume because of wiring harness trick? should i just get the SUPERTESTMODE and update this to the 2017 software 7.0? or just what should I do with this to get started, i just want to hack it all unlock everything etc. best software eye candy possible etc
