For the subjected issue ... i take up with Indus officials last week and yesterday some experts from supplier visit me with their updated firmware. They tried install new firmware in navigation unit, but problem is still there. They are very cooperative, they assure me to resolve the problem in coming week and also offer me to change the unit. They admit that they received complaints regarding the same issue but ........ hum nay kuch nahi kiya
magar ab karian *** 
They also update about some developments :
1- Web site will launch soon and all patches and other updates will available on one click.
2- They are working on upgrade android to Kit Kat. This update will free for existing users.
3- Soon they offer 9" display with DVD on some additional cost.
In the end they are very surprised to see push start and key less entry in my car.
I will update once i receive solution or some other development from supplier ...
