Garmin Quest input voltage

[colourblind]

Hi all
I'm new here...
I'm currently using a non powered RAM mount for my Garmin Quest, powered by the cable borrowed from the car mount, ie with the voice prompt speaker.
now, there's a voltage stepdown happening inside the voice prompt that turns the voltage from 12v to about 5, my question is:
is this necessary? can i take out the speaker and run 12v into the quest??

the powered mounts that you get seem not to have any transformer attached to the wiring.....

thanks

5v

The quest needs 5V at upto 1A. There's a regulator in the touratech/garmin/ram leads, and the garmin car speaker to provide this.

Edit: There's no regulation in the Quest itself. It'll go pop if given 12v.

Quest input

many thanks for this.
they do charge far too much for the cable alone. guess i'll just put up with the speaker dangling before the cig ligher socket for the time being.

thanks again

My suggestion (advice) is to no use the G auto mount to power the Quest on the bike. This has been discussed in the Forum, search in the forum on this topic.

As others mention and rightly so, there are powered mount options, some better than others.

Two simple points to think on. The G auto mount is for inside car use, not outdoors, so not weather/waterproof, second the Vreg chipset is different from the G auto mount and the G bike mount and same for RAM mount with GPSW QPAC. Both these bike mount have female jack sockets to act as an audio thru port for voice instruction.

To my best knowledge and depends on L-I battery state. The Vreg pulls 1.1amp, then falls away to 700mA on charge, trickles around 200mA. So remember when you leave overnight in the garage.
