Cannot acquire satellites and freezes

ok. go to garmin.com and download a new driver for it.

please do a firmware update sir

Make sure you are not moving. This way it can triangulate better. Wait for it to recognize at least 3 satellites. Then cruise as you wish as soon as it is synced with the satellites.
Also, be sure that you are on an open field with minimal aerial hindrances.

Your problem is normal to all GPS devices. It does take time to acquire satellite signal.

hope this helps!

The C330 does not have bluetooth capability. Regardless, this has nothing to do with the unit's ability to acquire satellites. Nor should the type of vehicle you purchased, unless the unit is unable to receive due to some feature, like something in the windshield, which is preventing the unit from receiving a proper signal. Does the unit work outside the vehicle?

Garmin nuvi
will not acquire satellites

Are you outside with a clear view of the sky? It should find satellites once the unit is turned on. Does it say "Looking for satellites" or "Acquiring satellites"?

If it is "looking for satellites" then it means that the unit have lost all data (time, date, location). If it is "acquiring satellites" then it have date and time, but not location.

Looking for satellites require a longer setup time (could be as much as 15 minutes). Acquiring satellites is much faster (not more than 2 minutes).

Date and time is updated from satellites once the unit gets a satellite lock.

To reset the unit, pry off the silver faceplate.
Turn the unit on using the power button on the right side.
Press the reset button that was hidden behind the face plate.
The GPS unit should restart, and display its software version.
Make a note of the software version in case you have to call customer service.
To acquire satellites make sure the GPS has a clear view of the sky.

Good luck, please rate this response favorably.

When Mine did that I bought an external antennea and now it works great

You need to go outside and turn on the Garmin until it has acquired a satellite lock (15-20 minutes). Kansas is the default location (Garmin Headquarters). Once you have acquire satellites, the Garmin will remember the last position as the starting position when the power is turned off. You know you have acquire a satellite lock once "Ready to Navigate" appears on the top of the screen.

You have to be outside with a clear view of the sky for it to acquire satellites. No trees, no buildings, no hills, etc...
