For the benefit of others, a quick couple of notes from installing my T7019a headunit

• Even though the unit is a 'universal Toyota' head unit and the mounting bracket fits the hole pattern, it isn't correct for the 86. (it is rotated and too far forward). I spent hours trying to resolve this by drilling extra holes in the mounting plate, but in the end it was simplest just to use only the bottom rear screw hole on each side (so only being held in with two screws). Despite this, the facia manages to hold the unit snug in place and it doesn't move.
• The default head units installed for NZ 86's seems to be the same as the one that comes in the Corollas here. When I took it out, there was a huge ball of additional wiring between the car and the head unit. I simply removed this extra loom - hopefully it wasn't important.
• I managed to install the GPS antenna on top of one of the air cond. ducts. It is important to give the curved part of the antenna as much view of clear sky as possible, so mount as far forward as you can. Don't mount it on its side, or upside down! The antenna seems to do a really good job of tracking satellites.
• Comparing the GPS speed with the dash shows quite a large discrepancy (dash is as much as 10% higher). Still need to figure out which is right, but I'm actually inclined to believe the GPS more.
• I didn't hook up the blue wire from the antenna adapter to anything (supposed to be power to antenna amp). Seems fine without so far, but then again I'm only a couple of km away from the broadcast tower.
• There are a couple of plugs (from memory, one on the car's loom, and one on the Toyota adapter loom) that don't end up being connected.
• I quickly rooted the device as per the instructions at the start of this thread. However, I noticed an option to change the LED settings/colours before the process, and it seems to have disappeared after rooting. (From memory, the options were 'Mono', 'Color 1' and 'Color 2')
• Despite the specifications my unit came with a HSDPA modem - still no luck getting it working though. @nzer - if you happen to be on 2degrees, what APN settings are you using?
• The right hand MicroSDHC slot was covered over (sounds like it may not have been in earlier units) - so didn't lose any cards into the unit during the install process.
• The /cache partition on the unit seems quite small (<50MB) - this may be the reason larger apps like Angry Birds Star Wars can't install.
• I've located the start up logos on the device. They have the extension .png.logo, however they are not .png files. Instead they are a proprietary palette-based format. I've managed decode them, and even managed to create a custom 86 startup logo.
• IMHO the default brightness is too high. It looks a lot better (less backlight bleedthrough), if you turn the brightness down a couple of notches.
