When replacing the cadence sensor battery, try to find a medical grade battery. It will last much longer.

Where do you get them? I think I just got a 2-pack from the local drug store.

I got them at K-Mart!

What is the equivalent number for a medical grade version of a CR-2032? Thanks for the tip!

[divingbiker]

You can get regular CR2032 batteries really cheap ($1.49 for 2) from roadid.com. (I use these in my flashing lights I wear in the dark, so I buy them 10 at a time.)

The number is the same. It will just say medical on the packaging.

When I initially bought my Edge, it only worked with PC's. At that time I had a pc, no problem. I've since changed over to a MacBook. Does anyone else use their Edge on a Mac?

I know this thread is about the 305, but does anyone have a 705? I'm personally curious about it. And yes, I know its excessive

I have to admit I'm curious about it also. It seems like a GPS-enabled device should have street maps, but if I really think I'm going to get lost, I'd bring a paper map. So it seems like the map would be useful once in a while, at best.

I've updated the mac software and can upload to training center and motionbased on my mac.

This is probably a re-post, but since I didn't see it on this thread, here it is again: when you park your bike, make sure your wheel and crank are aligned so that the wheel sensor and cadence sensor are NOT aligned with the pickup on the chainstay. If they are, the transmitter will continue to send, and the battery will go dead very quickly.

Same thing with the HR strap: don't put it on until you're ready to ride, and take it off as soon as you're done with your workout, even if you won't have a chance to change clothes right away. As long as it's on your body, it's sending and using battery.

oh, i remember reading that, but i think i also remember not really quite understanding (admitting to still learning a lot of the terminology).

Okay, I admit... since originally posting this (weeks ago?), I've gone back-n-forth trying to decide whether this was a worthwhile investment... It DOES sound/look cool as heck, but after reading/re-reading reviews from buyers on sites like Amazon.com and others, I have lingering concerns.

Do any of you think your speed is inconsistently measured? (the ones w/o the cadence/speed thingee) I've never had a wireless device -other than a hr strap- so it seems a little disconcerting to hear reviewers say its wrong a lot. I'm planning to just get the HR version - I don't really care about cadence anymore after having the PowerTap for so long. (its off the bike now)

Do you find the altitude measurement to be inconsistent? That's a lot of the reason why I'm considering this one over others. I wanna track climbing and know the gradient of the hill I'm on.

Mostly, I just want reassurance that you guys have been happy with the product (other than it just being cool, I mean). You don't feel like you need a cheapo Cateye on the bike to make sure the Garmin is right?

Sorry to be so questioning..those darn reviewers made me second guess my choice. But...I need to make up my mind quickly now b/c at the moment, my bike is nekkid - NO computer! Its like riding blind! It was nice for the first hr of my Wed night ride, but after that, I felt like I was really missing something.

[OakLeaf]

Before I got my 705, I did have a cheapo Cateye on my bike as well as the Forerunner 301, because the old Forerunners didn't have a cadence sensor.

There's a slight delay in any consumer-grade GPS realtime data - that's just a matter of how often it looks at your position and how long it takes the processor to interpret what it gets from the satellites. By "slight" I mean 3-4 seconds. Any time I was at a constant speed, the GPS speed reading was spot-on identical to what the Cateye read, and at the end of the ride, the overall distance was within a half a percent. The newer GPS units will be more accurate than that, both because of the more sensitive receivers and the more frequent recording.

Elevation isn't ever going to be perfect with a consumer-grade unit. Once you download it to where the computer can compare it against known map points, the accuracy is greater, but still neither perfect nor perfectly consistent.

If I were racing in the TdF, I'd probably have my team manager go out and drive the route with a $20,000 military/commercial grade GPS loaded in the car and then I'd know the elevation data was very accurate. For my own use (data geek mainly, and hopelessly directionally challenged), I'm absolutely delighted with my Garmin 705.

I rode with my cateye AND my Garmin for the first year and found the data very very close. My speed was always the same on both while I rode and my mileage was super close. I believe the elevation data is pretty accurate altho I imagine it's off sometimes. It always shows and the same elevation when I leave and any anomalies are supposed to be corrected when I upload to motionbased altho I admit I don't understand the process.

I love my Garmin.

Thank you thank you ladies!

Oak..the 705 looks DREAMY. Wish I could rationalize another $500 computer on my bike..but oh well, right? Since I don't often go long enough to get lost, I don't suppose I need it..though it would be cool! Perhaps I could make NEW routes easier with something like that though...

Your responses have been very helpful to my decision making here. Now I get to shop for the best price! Lowest I've seen so far on the 305 is $225. Not bad...

Thanks again!!
