Keep Android and 3G Dongle always ON

[diogo.hudson]

Hello guys I'm looking for a way to leave the 3G modem always on, even when the car is turned off.

any way to do this only in the software settings?

I really don't care to leave the android turned on in a fully standby mode.

The energy the appliance spends is much Less than the size of the battery in my car.

I'm using newest Malakya Rom. And the 3G dongle is connected in the 3G/USB Cable.

I don't want to make hardware modifications.

Thanks!!!

Justo to note. I stop, and leave my car many many many times in a regular day. And the 3G dongle takes about 1 minute to get Internet signal, so I can finally, get routes using Waze. Keep stopped in a car during 1 minute is not really safe here at Brazil.

I don't know about the 3G dongle. but the way I have mine setup the stereo stays on all the time. I have my accessory cable pluged in with the power cable. I have to manually turn the stereo on and off every time I get off the car but it's starts right away. and with an offline GPS app you don't have to wait for the internet connection.

Get a powered usb hub.
Use that between your stereo usb and the 3g dongle.
All you have to do is use a 12v usb car charger connected to your constant 12v then connect the 5v output to the usb hub.
That way when the stereo can receive data but the stereo isn't powering the usb hub or the 3g dongle.
