Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) What "port" are you connecting to? Would that be the USB port, or are you connecting to the "cradle" of the vehicle mount?
2) WHEN did this issue first begin?
Hi again and thanks for that information.
OK - WHEN did this issue first begin - or was noticed?
OK - has ANYTHING CHANGED with that cradle OR the power cable that connects to the cradle?
Also, MOST Garmin Power cables have a fuse in the tip of the adapter (where it plugs into the power socket) ... have you checked that fuse yet OR verified that there is power coming from the socket where it is connected?
OK - has ANYTHING CHANGED with that cradle OR the power cable that connects to the cradle - about the same time this started to happen?
That could be a short (or open) in the cable - OR - a short in the cradle itself - which does not appear when NOT connected to the power cable.
Do you have another Garmin cable you can try?
OR do you have another cradle that can be used?
Is that "No" to the cable, or cradle, or both?
And HOW is "Power is evident in cigarette lighter"?
OK - WHERE did you disconnect the power cable (cradle end or power socket end)?
AND does there APPEAR to be ANY damage or TWISTING of the cable at all?
And do you have the SAME symptoms (device stays ON) when BOTH ends of the cable are disconnected?
That is: Disconnected ONE AT A TIME..
I understand that the unit STAYS on when the cable is disconnected.
Is that true IF the cable IS connected to the cradle, but NOT connected to the power socket?
Interesting ... that sounds like this MAY be an issue with the cradle itself, and perhaps NOT the cable.
So let me ask if you have CLOSE EXAMINED the "contacts" of the cradle AND the device (perhaps with a bright light and magnifying glass) and if so, can you see ANY "bent pins" or any other "unusual" items there?
Also, have you removed the power cable from the cradle end, and looked that that connector too (bent pins, etc.)?
I have another TEST - that you MAY be able to do IF you have a USB-based power adapter and USB cord - such as what you might have for some Tablets or cell phones.
That TEST is to connect the USB cord to the CRADLE (not to the power adapter yet), and verify that the device STAYS ON.
Then remove the device, connect the USB cord to the power adapter (plugged in), and then put the device back in the cradle.
If the device STAYS on, and even takes a charge, we will KNOW that the original power cable is the issue.
BUT, of the device still turns OFF, then we will KNOW that it is the cradle itself that is the issue.
Does that make sense?
If so, do you have such a USB-based power adapter available to you - to do this TEST?
If you have to disconnect from our conversation - just come back when you can - so we can continue.
Please try that when you are NOT driving.
Take Care & Be Safe Out There, Greg A.
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
