I have an iPad and an android phone.
Can it be done?
It's the 800 so no Bluetooth or wifi
What phone ?
It is supports USB OTG then possibly.
Samsung s3 no idea what you just said 🙁
Dont think you can do it using either of those
Use a different computer...?
As it turns out I can copy info onto my work machine and then upload the file. It appears to be locked down copying data from it not too it.
USB OTG: it allows you to connect a device (eg your Garmin) to your phone so you can access the files on it. If your phone supports OTG(On The Go) then it works quite well. You can buy a cable off eBay for £5.00 or less.
This might help...

Keep meaning to try it myself.
I do it with my android tablet by always saving my data to the SD card in the Garmin, then putting the card in my tab, and uploading it to STRAVA from there.
