Garmin 800 Help!

Yet another Garmin help request sorry. Guys there was a link put out a while back as a rider had written a blog with all you need to know about the 800 etc. Try as I might I can not find the thread. Would someone be so kind if they are able to reply to this with the link.
Thanks

Dont know if you've bought or are planning to buy but look carefully at the various bundles. If you want offroad then the best bundle is the one with Discoverer map - its cheaper to buy this then add the cadence/HRM later than the other way round. If you want just road mapping, then look at the OSM maps for free and buy the basic unit without maps (with/without Cadence and/or HRM bundles). Note that the Discoverer OS maps are the 50k:1, fine for general directions but not the usual level of detail on a proper cycle map.
Since I am here, if anyone reading this is thinking of getting the 800, do it! it really is an outstanding bit of kit, and using Map My Ride you can create as many routes as you like, also if doing sportives they generally have a gpx file that you can use on your Garmin.
how do you open those gpx files without paying then?
I use RideWithGPS.com, works a treat...
