Garmin C330 Looking for sattlites comes & goes. Why?

Garmin does not provide free map updates. You may purchase map updates for your Garmin product at www.garmin.com , or by visiting a local GPS retailer.

mine is doing the same thing, it comes on , then goes right back off

Try to charge the unit for 4 hrs by using a wall adapter and then try power on it again and if still the same after you full charge the unit try to contact the manufacturer check if there is a latest firmware update for the unit.

Waking up your c330...

If you left your Garmin c330 on running the battery will have 1% life left. If you turn c330 back on again, it will flash screen for 3 seconds then die, even charging it at this point will not wake it back up. TO BRING IT BACK TO LIFE... plug in the power home or car into Garmin c330. There is a tab in the front Garmin gray frame of your screen. You must take like your fingernails and under the logo "GARMIN" pull the whole gray plastic frame off. Underneath the plastic frame to the right hand side. There is a "RESET" button. Make sure power is plugged in while hitting reset. Your battery should come back to life. Cheers

I updated my Garmin by going to its web site and searching it till I found the free update instruction. Of course, your Garmin has to be connected to the computer first.

There are no free map updates for the StreetPilot Series.

The newer models do come with a free update that must be downloaded within 60 days of purchasing the system.

There are utilities for adding POI (Points of Interest) as well as Browser plugins that can be used to add Favourite Locations from Google maps. these updates are available from the garmin website.

You need to replace the rechargeable battery. I am looking for one now, as I have the same problem. you nee a 3.7V 1.8Ah Lithium Ion RECHARGEABLE battery, it is 65mm long and 18mm in dia. I'm not having much luck and Garmin want $150.00 for this repair, IF YOU ARE OUT OF WARRANTY.

I have no signal or one small red point.The GPS shows looking for satilite and that is it.
