I puzzed why entering navigation (Google or Premium...same issue) doesn't automatically turn on the GPS and disable it on exit. The car panel setup allows for automatic turn on of bluetooth, but again no automation of GPS turn on/off. So I'm wondering if there an app out there, that will turn on GPS when charged and disable it again when disconnected from the charger? That would do the trick IMO.
Also, if anybody knows of an app that will automate syncing of the standard accounts (i.e. stock, exchange, facebook etc.) depending on time of day and weekday, I'm very interested? Exchange ActiveSync could be ex. be synced "upon new mail" during 8-17 and in user defined, reduced intervals (hourly, every 2 hours etc.) or completely off for the rest of the day/night. You might want to get updates on facebook, gmail, sense, news etc. a couple of times during workhours, but then more frequently when off work. You might change setting for the weekend and hollidays. Could be a very neat app - if it's out there?
