Just brought a RAV4 and a QL-RAV977. Will be installing on the weekend and looking to spend time hacking the unit to run a different shell full-time. Also looking to replace the iGo software with TomTom Navigator
i believe the software boots from a read-only portion, meaning any changes you make whilst unit is operating will work, but once power down, it will then reset. That is why there is the Static Store, so you can store something on the unit.
