Hi, I managed to lose the suction dash mount for my Garmin Nuvi 3760.  I ordered another from Garmin and it didn't come with the mini USB cable that plugs into the cigarette lighter.

For exactly the same amount of money I could order the cable from Garmin but was wondering it I could get it cheaper elsewhere.  Have looked at quite cheap ones that put out 5 volts but I think my model of Garmin needs more power.

Does anyone know the type of car charger cable that I'm after?

If it actually is a USB connector then the voltage is defined in the USB standard, not by Garmin. You can test this by connecting it with a standard USB cable to a PC and it should charge the battery. (It will also go into mass storage mode; you may have to turn it off.)

My Zumo happily charges its battery off my PC using the USB cable.

Alas my Garmin doesn't hold its charge at all so I need to keep charging it while driving.

There is a micro USB cable slot to connect to PC and charge but it goes into stand by mode when you do that. The mount has a mini USB slot in it so it can charge while driving without going into stand by mode.

When I was looking at the generic cables in the electronics store they reckoned that 5 volts wouldn't be enough. But I do think the price from Garmin, just for a cable, is ridiculous. Especially that when I bought the dash mount I was really surprised that it didn't come with it.

I could just buy a $5 charger off TM just to see if it works and save myself $50.

What happens when you put it in the mount and connect that to the PC?

The mount has a mini USB slot and the actual unit with the screen has a micro. I haven't got a mini USB cable to try it with.

The cheap one(s) on TM list compatible models. There are Garmin models listed there but not my 3760.

I want a generic mini USB car charger that isn't the standard 5 volts. Not to be found in my local tricky dickies. :)

All USB chargers are 5V, if it's not 5V it's not USB. The current may vary it could be a high current device and take 1A but I doubt it.

Ok, thank you. So I don't need a special one from Garmin then. I'll have to let them know the generic one would have sufficed.

Cheers for that :)
