Garmin Edge 705 Discontinued

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Garmin Edge 705 Discontinued

This is probably old news, but the Garmin site lists the Edge 705 as discontinued. Only the 800 and 500 are available.

The 800 is a fine unit, but I still don't like that the virtual partner distance ahead is only displayed on one screen, unlike the 705 where you can get the distance ahead along with quite a bit of other data.

This explains the very cheap 705 deals around at the moment

I went with the 800 and, after a couple of rounds of setup tweaking, love it. Wish I hadn't waited so long to buy it.

The problem with the Edge X05 series (205, 305, 605, 705) was their GPS chipset. It's the Sirfstar III chipset which was more power-hungry and less capable. The X00 series (200, 500, 800) have a Sirfstar IV chipset which uses less power, enabling more features (like touchscreens, etc), longer battery life, more sensitivity to keep satellite lock more reliably, and most importantly, HotFix, which is stored/predictive ephemeris data, cutting approximately 30 seconds off the lock time of each satellite if you're in the same position as when you last used it.

Ever notice how smartphone GPS will get position almost instantly? It's because the ephemeris data (current satellite orbital position) can be downloaded instantly from the cell towers over a highspeed wireless network instead of slowly (~30s) over the satellite signals. Most handheld standalone GPS receivers can't benefit from this so things like Hotfix have been developed to aid with it by storing ephemeris data between power-off and power-on events.

That sounds all good, but doesn't solve any issues I've had with 705s. I've not had problems with speed acquiring lock, keeping lock, and find the battery life quite acceptable. Issues I have are with firmware and navigation bugs, the proprietary maps, etc.. Seems the 800 is rife with bugs too.

Cool tech details, thanks... you learn some new every day.

Keep an eye on Nashbar if you're interested in a 705. I picked one up for $329 last week.

I have a 705, 500 and 800. I've ridden more than 5000 miles with my 800 and I haven't had problems with mine.

You can download open source maps if you don't like the proprietary ones...

That being said the 705 for $299 is a great deal.

Yep, definitely the way to go. My 800 came with the city navigator data card, but inexplicably, the bike path along the lake here in Chicago is NOT listed!?!?! This is a bike GPS! Also found many other cases like this. Open source is free, updated, and most importantly, actually has paths that a BIKE might use in addition to streets.

The X05 series may have inferior chips, but I have had no issues with mine. Its much more accurate than my cell phone GPS. When you first turn it on, it may take 10 - 20 sec to lock, but once it does, it has always performed perfectly for me. I dont ride in much tree cover, but I do go through downtown with tall buildings.

Perhaps "inferior" was a bad way to paint it. The newer chips are just more advanced with broader capabilities, similar to what happens in personal computers. New things coming out do not diminish the capabilities of the prior models.

That's how I took it. I was just making the point that while there maybe something better, the older one is still really good too. Battery life on the 705 has been more than enough as well. If I didn't already have one and saw a deal on one cheap, I wouldn't hesitate to snatch one up.

How are real time battery life estimations on the 800 vs 705? I found Garmin way overstated on the 305 so is this also the case with 705 and 800?
