Another backward step Mr Garmin

In the old days (2003-2008) you connected your GPS to your computer with a cable - originally serial RS232 and more recently USB.  This worked fine.  Drop the GPS into the cradle, hit upload and then wait 10 seconds and it is all done.

Now however Garmin have this fantasy that you walk into your house after a refreshing run, your Garmin GPS automatically pairs with your Garmin ANT stick and before you have taken more than a step across the threshold all your run data is uploaded, via your PC, to the internet.

An ANT USB Stick - Garmin Flavour


Does not work.  So does not work.  I spent hours searching the web and this revealed many folks having no end of trouble with wireless transfer.  "Leave it next to your PC go and have a shower and, hopefully, when you get back the upload will be complete".  I tried all of the fixes, rebooting, uninstalling, reinstalling*, upgrading, forcing upload (start and stop and reset your GPS) - no luck - and then on an obscure site there was a mention of "interference".  But surely not - ANT is designed to be robust and to laugh at interference...

310XT - strong but silent. Data goes in but it doesn't come out


*Did I mention you that the web page listed in the documentation that comes with the 310XT directs the purchaser to download drivers from a page that Garmin no longer maintains - you just get a 404.


According to the ANT website

"Reliability and Dependability

ANT has several mechanisms to protect against interference including the unique adaptive channel synchronization technique, as well as frequency agility. On a given frequency, more than 100 ANT channels can co-exist harmoniously within the vicinity."


Well Mr ANT  my 2.4GHz wireless router, DECT phone and HP printer get along just fine but the only way I can get my ANT stick to discover my Garmin GPS (310XT) is to turn everything wireless off and then do something like this... 


Yes - if I shield GPS and receiver inside my Trangia kettle and Cookset and put both lids on - the devices will pair and transfer data - but still VERY SLOWLY
What was wrong with wires?

by the way - the 310XT is excellent - just let down by connectivity
