Reusing TomTom power cable for a Garmin sat nav?

Hi.

I wondered if anyone might be familiar with the spec of this male 12v connector plug please, which connects to the female socket of TomTom's powered mount for a Rider 550 sat nav, that I've been using for ages.

I am moving over to a Garmin Zumo XT2 and wondered if I could reuse my power cabling for the TomTom, by putting a compatible female socket on the power cable of the Garmin mount?

Cheers

The zumo xt2 operates on a 12v supply, although the older xt is 5v. I THINK the tom
tom also operates on 5 volts not the 12v that the xt2 requires. Hope this helps.

Thanks.

Yes, and I believe the mount for the TomTom Rider 550 converts from 12 to 5v to power it.

Both the TomTom and XT2 cables are 12v in other words, which takes us back to the question about the cable plug and socket

Mmm, yes quite right, unsure on that one, hopefully someone will be along tomorrow.

Let's see. It's a type of twist lock barrel connector. But is it a non-proprietary type?

I've been told that these barrel connectors are a TomTom patent design...

So the only way I might get hold of a female connector would be to remove one from a Rider 550 dock (same one as for the 40/400/410/500).

If anyone has a knackered TomTom dock they do not want, please get in touch!

Ta!
