Question about Garmin StreetPilot c550 GPS Receiver

C550 loses connection to satellite

Intermittent loss of link to satellite.  After a while if there is no downlink, the unit will go into automatic diagnostic routine... asks if we are inside a building (no), then asks if we are in Georgia (yes).  Very unpredictable.  Even fails out on open hwy without a tree or bldg around.  Unit sits on upper dash of 2008 Toyota Highlander.  Have not tried any resets, update of firmware, etc...just bought it less than a month ago.  I have an old Magellan that has worked like a charm...only problem is updating database.

I finally found out what the problem was re the BMW. The antenna has to go at the back not in the front. The windshield was interferring with the satellite signal. Works great now on the BMW.

Recently when returning from a trip my C550 giving keptme the message "satellite unable to locate" (not the exact words) This went on for a week or more but suddenly started locating me from the satellite....


Low battery power is generally r4esponsible for loss of signal or low signal. Charge itr fully before use and plug into car power source ONLY AFTER staring the engine so as to avoid spike deamage. The car charger cannot fully charge the battery it is justn sufficient to maintain a level of charge . If the battery gets too low it cannot maintain a constant signal.

to reset the c550 place your thumbnail in the groove located under the garmin logo on the faceplate. Gently pull off the faceplate and press the reset button then connect to a power source and the unit should automaticly turn back on.

Cant connect to satellite.


Ok, sorry, I noticed the "Can't connect to satellite" right after I asked the problem. Have you tried a Master Reset yet? Be aware, if you do this, it WILL ERASE ALL OF YOUR FAVORITES. If you need to reinstall the firmware, you can do this at www.garmin.com. You have to download WebUpdater, then you can install updates, or reinstall the current firmware edition.

Bluetooth connection


If you have tried to connect from the unit and from the phone, and neither finds the other, or they won't connect, it is possible the phone may not be compatible with the unit. Not all Bluetooth devices are compatible. Your best bet would be to go to Garmin's website and check the C550 for compatible phones and see if yours is listed.

Satellite loss


How long has it been since you updated the firmware on your unit? Try updating and see if this helps. Also, keep in mind the receiver on the C330 is not as sharp as on other units like the C550 and some of the Nuvis. You may have problems while under overpasses, between large trees or buildings, etc. This is just a design limitation of the unit.
