Re: screen says memory full and it won't map a route!...

Hi, Please do not shoot the messenger (me) but this is a known problem with Garmin GPS units. According to Garmin Tech Support, this only occurs on Garmin units with older firmware. (Personally, I am not convinced this is actually true. I no longer have my Garmin C550, which I personally liked the best out of all the GPS units I have owned or used. I will buy another Garmin, probably a Nuvi, when this silliness sorts itself out.) Anyway, you have two options, neither of them acceptable to most people, including me. 1)Perform a HARD RESET which will wipe out all data on your unit, including your favorite points, Bluetooth connections, and almanac data (satellite information). Your unit will then need at least 40 minutes, with a clear view of the sky, to update the almanac and reacquire its location. To HARD RESET, unplug your C550 from the charger and turn it off. With the C550 screen facing you, press the bottom right hand corner of your screen and hold in (relatively firmly) and then press and hold POWER. You need hold both constantly for at least 30 seconds. Follow the instructions on the screen. See if any of your personal information is still there. If there is none, then you might as well perform Step 2 below. 2)Download and Load New Firmware onto the C550. Upgrading firmware is relatively easy provided you have a computer. Visit Garmin's website ( Go to "Support" .. "Updates and Downloads" and then click "Unit Software." Download the software called WebUpdater. Run that and follow its directions. The new Firmware (Software that is loaded into internal memory that does not need power to remember the information) hopefully will fix the MEMORY FULL problem. Good Luck and please post back if the fixes helped or not. I really want the new firmware to work so I can buy another Garmin.

This is an indication that the map or map unlock key is either missing or corrupted. If you have registered your unit with Garmin, try connecting to your PC and try downloading the map again. More info on missing maps can be found here:

Can't find State or Province

The C550 does support USB 2.0 so data transfer of the Maps was most likely faster. The newer USB drivers from Garmin is most likely USB 2.0 compliant. Perhaps they didn't fully test it for USB 1.1 Anyway it's working for now. Usually I go to setting Map, Map info to verify that the upgrade was successful.
