Garmin: I learn something new all the time...

Major DUH moment...I am apparently NOT as slow on the indoor bike trainer as I had thought. I noticed that even though the current speed on my Garmin (Forerunner 305) usually shows in the 14-16mph range at cruising speed, but my average never is more than 13-13.5mph.

I also notice that that average speed will frequently drop to the 2-5mph range for several seconds, even though the cadence remains consistently in the 90-100rpm range on the middle ring.

I did some Google sleuthing and discovered that there is a way to shut-off the GPS sensor for indoor workouts. Apparently my Garmin was grabbing a satellite connection here-and-there and it was canceling-out the cadence/speed/distance sensor on the wheel and messing with my average distance and speed--not in my favor. Ahhh...

Hope this helps someone else. I wish Garmin units shipped with an actual paper manual to reference in a pinch (I'm finding this criticism applies to a LOT of things, nowadays--I'm old skool).

I just figured that out too!! This frustrated me for the longest time...:rolleyes:

When I got mine at the end of 2008 it did come with a paper manual.

My 305 always asked after a while "Are you indoors? yes/no" but I was biking in the basement.

Mine asks me this maybe 25% of the time. I never realized there was a way to just flat-out tell it. I am so geeked, now! :D

I got mine in '07 and it didn't come with a manual...how'd you get so lucky? I wish things still came with paper manuals. Drives me nuts when I have to load a CD-Rom or look online.

Mine came with a paper manual, but I find it usually not that helpful. More helpful has been the user forums on Motion Based (I'm not sure if that is the same name these days). The first time mine would not turn back on after charging, I freaked out. No mention of how to reset from Garmin, but I got the answer quickly from checking the user forum (push in the mode, lap, and power buttons at the same time). I wish the "GPS off" setting was a little easier to get to...

I agree that the GPS off mode is hard to get to and the paper manual that came with it isn't very detailed. I will have to say that the support on their website is very helpful as is customer service. It's nice to be able to call a company for assistance and talk to someone you can understand.

Here you go. All the manuals for download and printing.

I find that I have to use the manual, Garmin's online support and various forums. For instance, info about gStart for GTC can't be found through a search on their site.
