He's talking about whether his nuvi runs DIRECTLY off 12v and, as I said, that will fry the nuvi :twisted:
Incidentally so would 24v :evil:
He says he needs to replace the 'plug', he asks if the voltage FROM the plug is 5v or 12v. The answer is 5v.
Simples.
I agree a genuine Garmin cable steps the voltage down to 5v, but that wasn't his question, and in any case it still makes the answer 5v.
1. Why would anyone need to replace it?
2. If it is dead than isn't there a fuse that needs replacing?
3. If it was stepped on and is broken shouldn't the owner buy a new Garmin power cable for the cigar lighter?
MY first read was the poster's female cigar lighter receptacle went bad; not his Garmin plug. If the plug needs replacing and the fuse is not open than a new Garmin power unit is needed.
4. Where do you ever buy a 5V male cigar plug?
Isn't the voltage step down voltage regulator part of the Garmin 12V power cable?
Me dumb!!!
:roll: :wink: :lol:
If it's in the plug and it's ruined, he can always pick up a 7805 while buying a new plain plug.

It's best to replace the fuse or buy a new power cable.
:D
The Garmin male cig plug adapter plugs into the female cig receptacle on the vehicle. The large plug adapter contains the step-down circuitry necessary to convert from vehicle voltage to the approx. 5VDC the GPS requires. As mentioned earlier, that can be 12/24 VDC input (to the adapter).
As I read from my cig adapter in front of me now, the specs are:
Input: 10-30 VDC, 1 Amp (max)
Output: 4.75-5.25 VDC 1.0 Amp
Fuse specs: 1 Amp/250 VAC
Therefore, answering Alfred's question, the voltage output from the plug to the 1490t is approx. 5 VDC
but thanks for clarifying it for everyone :lol:
Using 7805 for this application is a bad idea, it will get quite hot. Easier would be to buy whole supply for usb device and replace wire and plug with original from defective unit. Supply should deliver up to 1A, which is above the common value for mini-USB.

In 1490t car power supply include TMC receiver. This will be more expensive part than simple supply. And it contains all TMC subscriptions you bought, buying an new one you will have to pay for subscriptions again. I suggest to call Garmin support and ask about repair.
But check the fuse first, this you can replace yourself :)
