Garmin or Magellan? What works best?
In the last 2 years, I've had 2 different Garmins. Both failed in about a year. I got both at Costco and they refunded my money on both. Now, however, they're not carrying anything but a single high dollar unit that I'm not interested in.

How & where you going to use it?

I'm talking about one for driving.

Can't comment on the Magellan units, but I've been very happy with my Garmins. I'm on my second (upgraded to larger screen) and my wife uses one as well. Both of our current Garmins I bought as refurbished units with free lifetime map upgrades for under $100. Never had one fail. Bummer you had 2 go out.

It appears to be a battery problem. If the battery won't charge, it won't start. Possibly the batteries fail because we only use it a few times a year when traveling and the charge gets too weak.

Started with Magellan's years back, but switched to Garmin in the interim. Just found the Garmin's a little more intuitive.

My old gps's stopped working.

I got a couple of Tom Tom gps's for the car in the walmart.

They work now. These have a 5" or so display and plugs into the car's 12V.

I have 2 Garmin units one is 7 years old , the other is 2 years old never one issue on either. The older one of course takes longer to update maps but that is it.

Carmin has kept me on track for a decade, no complaints.

I think i have four Garmin units bought at Costco for the various delivery trucks etc. The only one that has failed in the one my son left laying on the floor of the 2-ton all winter.

Some are much easier to use than others.

You may want to try replacing the 12v charger cord. We thought my wife's wouldn't hold a charge but when I hooked it up to the 120v charger it was fine. We got a replacement 12v charger cord for under $10 on Amazon, I think.

It was still under warranty so I swapped it for a new one. But then, when I was programming in the addresses, I found that Garmin's latest map update moved our house 3 miles, along with several of the neighbors' houses. I reported the error and supposedly they'll fix it on the next update.

If you ever unplug the unit from the car's outlet and let the internal battery run completely dead you have to press a reset button to get it back on. More than likely the previous 2 you owned did that and were fine.

I have had the same unit in my vehicles for years and found out about that the hard way. I thought mine had bought the farm when it stopped working. I was coming back home to GA from a hunt in CO. My BIL unplugged mine to punch in something and never turned it off or plugged it back in. We didn't need it for several hours and it wouldn't work when we did plug it in. Got on the wrong road coming through St. Louis and cost us about an hour. My BIL figured it out and it has worked fine since. That was 2010.

Garmin has been good to me. I broke the screen on my handheld, a $400+ device and they sold me a new one to replace it for $100.
