Bests & Worsts Reviews from Amazon

I bought the 605 for a couple of reasons. First was the turn-by-turn directions. What Garmin is vague about is that to get turn-by-turn directions, you have to buy their City Navigator Map card for another $100. Ok, fine. Bought the map. First attempt at getting directions - picked a destination 25 miles from home (nothing too difficult, as a test). The unit literally took 23 minutes to plot the course. 23 minutes! Unbelievable. Car navigators take seconds. Once the unit plotted the course, I noticed that it took me through the Holland Tunnel (leaving New York City) and on a freeway. Not exactly how I pictured my first bike ride with the thing. Ok, so maybe the plotting doesn't work so well. I figured maybe I could just create routes on my computer and upload them to the device. Nope. Not possible. I took a closer look at the manual. No help whatsoever. It's a joke, actually. On-line help? Ha. Go to Garmin's website. Download the manual. Try to find any good, specific, detailed information on how to really use the device. It's not possible. Somewhere in the Amazon listing, Garmin also promises SPOKEN directions. Nope. Totally not a feature either. It's really amazing how bad this thing is. It does almost nothing except tell you where you are. Which is what my $90 Garmin Geko did 4 years ago. As for the cycle-computer functions, I got better data with my $30 Cateye. The Garmin's data is very slow to update and the altitude was always wrong. The unit doesn't come with a heart rate strap - and I didn't expect it to. But if you ever want to upgrade later and add one - forget it. You need the 705 for that. I really can't believe what a piece of junk this is. Also, it lets you set the backlight level - nice feature, except that whenever you turn the unit off, it forgets your setting and reverts to no backlight. So everytime you turn the thing on you have to reset your backlight setting. Arg. It is true that you can log on to Motion Based (Garmin's GPS web-community) and download other users' routes. But the unit will only hold one at a time. And there's no way to edit the routes. You can't edit your own routes on a computer either. So frustrating. I've never been so underwhelmed over a product. Here's all I want (Garmin, are you listening?): -Decent turn-by-turn directions. For a BICYCLE. And instantly (or under 2 minutes). -Ability to download routes I've ridden and edit them, then upload them back to the device. -Ability to create a route from scratch and upload it to the device. I'm not asking for much. This thing does NONE OF THE ABOVE. Whatever you do, don't buy this thing. Unless you want to buy mine on eBay.
