The navigation system has been updated. Previous one with trouble had iGO2 sticker on the bottom lip protruding from dashboard (same side where serial number is also attached). The current one is iGO3.
I have been using it for some time now. The operating system has been updated to ICS (v4+) from Gingerbread. Now, if you shift into reverse within a certain time frame after the car is started, the display shows reverse camera feed with cropped/thick black edges on left and right sides. It is unprocessed grainy video (low quality) and doesn't seems to be coming through the android operating system. It is a hit and miss, i.e. sometimes it doesn't sense the shift and keeps loading the OS. If it starts loading the OS, you won't get the feed until the OS has fully booted just like it did previously. The quality of the video feed is still the same as the older navigation unit and the camera still points too low making it impossible to see any cars coming from the sides. The field of view still covers very limited area, unlike the previous much better camera angle in the City's navigation unit. Once you shift to D/forward gears (in manual variant), the view shifts to the front camera automatically for some time until the unit completes loading the OS.
The UI is improved in some places and same in others with regards to responsiveness. There are still useless icons and apps on the screen (My Car and other similar stuff) which have no current use. According to a representative, there will be future expansions offered later on like TPMS, etc which will be used through the currently useless apps and icons but I don't think I will be able to trust them or be comfortable letting them screw up the car's systems like they initially did with the Navigation/multimedia unit. The only two useful things are Media and Phone (Bluetooth) right now. Also, I was told that the unit must be manually switched off by pressing the rotating dial every single time before turning off ignition to prevent damage to the unit.
