You might want to check the condition of your USB adapter is working properly. You may also want to consider using a Mac software called Android File Transfer (by Google). It works for any Android device (including the Samsung Galaxy series), and you can easily move files to/from your Mac...see Related Links below. Also, if you want your music easily played everywhere, you also might consider Google Music. You can upload music regardless of what platform you are at to the service, and then once uploaded, can be streamed on any device or desktop/laptop with no platform restrictions.
Some computers store the time with the help of a small internal battery known as the CMOS battery. The small battery will keep the clock of the computer running even if power is disconnected. If the computer are disconnected for to long however, the battery will run out and the time and date will be lost. If you are having problems with the time and date of your computer you should check that this battery is still working properly.
On older vehicles, it would usually mean that the speedometer cable is broken or disconnected. On newer vehicles it would probably be a computer problem.
May be you accidently disconnected a sensor wire doing the repairs. Maybe you have to reprogram the vehicle computer because the battery was disconnected. LOL
Most likely the reason is when the battery is disconnected, there is no power to the PMC. On this car, you may have to reset the code, or chip...Try to disconnect the negative cable, and have the key in the ignition (KOEO), it may wqork...Tom..
Disconnect the battery and wait about 5 min, this will reset the computer and the 4-wheel drive should work.
If working on the electrics of a car then it is a sensible precaution to disconnect the battery.
Yes, my computer is working properly.

This light will always be illuminated as long as the camera is connected to the computer, so it will go off if you disconnect it from the computer. If it must be attached to the computer, you can turn the camera away from where you're working, or cover the light with something so it can't be transmitted.
It does no harm to disconnect the battery when working on a vehicle but in general no, you do not need to disconnect them to change a filter.
If the speedometer in your Voyager is not working, you might have a problem with a disconnected cable or with the fuse to the display. You could also have an issue with a sensor.
