I recently bought a AP2 for my 06 wrx. It's unmarried/uninstalled. After updating the firmware to the latest one (1.6.4.0) i tried to install the AP2 while the car's in test mode, and after the AP2 identifies my car (USDM 06 WRX MT) i continue. Then i was prompted to choose a map. All the maps are grey'd out making me unable to choose and continue and underneath each map says "invalid lock". I NEED HELP ASAP !!!!!
