The present invention provides a method of operating a telematics enabled mobile vehicle communication system. The method includes receiving a vehicle power down signal that includes vehicle identification information and time information of vehicle power down from a telematics device to a service provider. The method further includes initiating a vehicle power down count down at the service provider responsive to the receipt of the vehicle power down signal and estimating a remaining vehicle connection availability window based on the vehicle power down count down. The method additionally includes populating an advisor application with an estimated remaining vehicle connection availability window that is based on the vehicle power down count down. The method may further include generating the vehicle power down signal with the telematics device when a power down mode in an associated motor vehicle is detected and communicating the generated vehicle power down signal to the service provider.
