My Leviton VPT24 Outside light switch went totally blank. The light do not turn on. Is there an internal battery?

While standing at the switches (outside the room) turn each switch on until the light is activated. You need not be in the room to see the light operating.

Is this a new installation? New installation then wiring might be bad.
Or older installation that has stopped working? Timer might be bad.

The Leviton 6124 is rated for incandescent light bulbs up to 1200 watts, and does not appear to be rated for CFL, but could possibly work with CFL and LED.
Change bulb to incandescent.

Copy following link to identify timer, and correct wiring.

Aube/Honeywell timers have internal rechargeable battery that powers the display.
Battery is not replaceable. Plus the electronics inside timers are susceptible to power surge.
Without the display, timer cannot be used.
These timers come with standard 1 year limited warranty.

I think the matching remote totally matches down to the LED display of light level. Coordinating remote does not have the LEDs.

I think you are saying that you have 1 romex-cable entering box.
And that 1 cable has a black, white and bare ground wires.

Here's how to wire Leviton's vpt24 timer.
Timer has Red Black White and Green wires.
Connect White and Green wires to bare ground wire.
Connect Black-timer wire to black wire inside box
Connect Red-timer wire to white wire inside box.
Turn power ON, and try timer.
If timer does not work, then reverse Black-timer and Red-timer.

Here is photo of similar wiring using Intermatic timer

Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on timer or any do-it-yourself project.
Fixya is always less expensive than a service call.

The white line should go to the white screw.
The black hot line should go to the brass (gold) screw.

The Leviton 6696 Anywhere RF(Radio Frequency) lighting control allows you to add an additional (wireless) switch to an existing switched light(s) without having to hard wire it. For example, let's say that you have a bedroom with a switched overhead light. The Leviton 6696 RF receiver would be installed in place of the existing light switch. It will still function and is wired the same as an ordinary switch. The Leviton 6696 Anywhere RF transmitter (after installing the batteries) can then be used anywhere within 50 feet of the receiver (that replaced the existing light switch) to also control the light. You don't have to mount the transmitter if you don't want too. It can be on the night stand, (or carry it with you if you want) so you can turn the light ON and OFF from the bed or wherever.

The blue wire is the switched hot wire coming from the leviton.
So:
black hot/source to black leviton -- blue leviton to black for light fixture or black "line" on GFI -- all whites connected together.

P.S. If the GFI is only powering a light fixture, it is not needed.

most Garmin's are powered by external sources which charge the device. the device has a battery internally and is kept charged by such a cable connected to the cigarette lighter socket.

If its a built in Garman then most likely its the fuse.
