• Yeah, all the Garmins I've owned have worked fine with any external pack I've used. The 1000 was the only tricky one coz you needed an L-shaped USB to clear the bar it was mounted to.

    What ancient Garmins are you talking about? You can probably avoid this with a USB data blocker - I've got a couple of these myself. Useful for using public USB charging when you don't want you phone contracting any malware from the "please hack my phone" charging spots.

  • 705s. They used to work fine - done charging on the go on PBP, TCR, IndyPac, audaxes, etc. But they don't work any more. I've got three of the buggers so it seems like some systemic thing as it has happened on all of them at the same time, like Garmin has saboutaged the firmware to make luddites like me upgrade.

  • Ah, they really are old. I bet the connectors are worn or have corrosion on them. You can try isopropyl alcohol swabbing inside the connector. I also got some mileage out of my 800 when it got wet and the connectors oxidised, by scraping them with a fucking stabby thing, what do you call, a pin! Scrape the things with a pin and try the connector again.
