I don't know whether they still make the Garmin
Of course not.
It was too simple and reliable. No...they just had to release the 510 pile-o-problems just so they could offer the craptastic and phone-like Touch Screen. That only took twelve 'taps' to get it to change screen. Or freeze up...whichever was more inconvenient.
And then...
The released the 520 and completely stopped supporting both the 500 and the 510.
Actually, Garmin did get most of the bugs worked out of the 510 just before they released the 520. If they could pack all of the 1000 into the size of the 520 I would buy one of those, too.
I really want to like Garmin Edge units, but they are as buggy as any electronic product out there these days. Hell, just this morning I bought my THIRD dehumidifier in the last 6 years. Great track record for quality, huh? And I doubt this one goes three years. It's all crappy Chicom junk (and G.E. just sold the appliance division to Haier??? God help us!). My first was a Soleus Air that burned houses down. Don't believe me? Google it. That took a class action lawsuit to resolve and I got my money back. That bought me another Chinese junker that lasted a couple of years before going tits up. Extended product replacement warranties are our only hope...
Back to Chinese computers for the bike...
The 520 does give you mapping, if not turn-by-turn navigation...yet. It still lacks memory card capability and for what reason Garmin doesn't build it in I have no clue. I will say that in Winter gloves the touch screen 510 is easier to use than the ****ing SEVEN button 520. Those buttons are small and take some decent pressure to accuate. With heavily padded or multiple glove layers it can be next to impossible to use the buttons.
The 500 was fairly solid. The 510 suffered a history of problems both resolved and unresolved. We'll see how the 520 does as Spring comes and goes.
I tried to like my Cateye Stealth 50 as I had great luck and good life from the several Cateye Strada Wireless units I had and still have. The Stealth was fairly solid and the features were 'almost' there. Sadly, the interface to the PC and Cateye's Atlas website were not up to snuff. I only managed to force myself to use it for about 9 months before I gave up in frustration and bought the Edge 510. My frustration continued...
