I've seen evidence of BRZ owners updating their audio unit via USB for free. Not interested in the Nav updates - was just hoping to get a more solid bluetooth connection (it's very flaky) without having to buy a new unit or pay Toyota for a patch.
Hi from Australia - recently got an 86 GTS (I think this is the standard UK spec) and wondered if there's a way to update the firmware for the infotainment unit (last updated in 2012.)
Thanks!
