Worked for about two weeks. Got a message saying "No maps found, can not work without them." That's it. I have been trying to solve this problem for a few hours now, and this seems to be a fairly common problem, with no solutions so far. You would be a fool to buy this, or any other Garmin product.

This was a refurbished unit which made for a nice cost savings. I had assumed that it would have the current maps installed, which was not the case. My area (Phoenix) has had a fair amount of growth in recent years and I've found numerous instances where businesses and addresses that were put in two years ago are not in the database. It's a little frustrating to be faced with having to buy an expensive update for what should be a new/current system.

Operation wise the unit works fairly well. Going through a complex freeway/overpass the system will may give an accurate instruction for an exit to take but too late to actually take it. It's not readily easy to put in and label a current waypoint - one has to provide a street address which may not be readily available.

All in all it's a decent system that would be improved by having a switchable ETA/miles to destination option, and an altitude readout.

If your looking for a basic GPS unit without a lot of bells and whistles this is perfect. Two other family members have bought this one and love it.

I have mine for about a year now and it takes me whereever I need to be. I have added a SD memory card and loaded the maps of Europe and South Africa as well - everything works beautiful. Whenever I travel, I just preprogram my destination addresses into the GPS - when I pickup my rental car, I plug it in and it takes me straight to where I need to be - very nice after a long flight when you're tired, in a foreign place and just want to head straight to the hotel to crash. This has worked every time from Honolulu to Amsterdam to Johannesburg.

There may be flashier models with more bells & whistles available, but the c530 is all that I need.

If you need to go all over in your city to places that you have never been to before this thing is the best ever. I have been using for about 4 months to find addresses of homes for my job. I would have to say it payed for its self just in gas savings in 2 months. you figure if you waste 30 mins a day driving around lost at 15 mpg that could be 2 gal. of gas at 4.00 a gal that could be up to $160.00 a month in wasted gas. plus it is very easy to use. like any computer you put in bad info you get out bad info.
