If the above procedure does not work for you, the entire antenna assembly will need to be replaced.
The other option is to purchase an external antenna for your Nuvi and plug it into the external antenna port (gold connector) on the Nuvi antenna assembly.

Best wishes,

    If you can pick up signals with a piece of wire, the external antenna will out perform the internal antenna.



    Good luck!

Does your Garmin Nuvi 1200 Freeze at Loading Maps?
Does it lock up or stop working?

This tip will describe how to perform a hard reset of the device, and how to backup your 'Favorites' in case the hard reset erases them. The next step in fixing your Nuvi when it doesn't start properly is to update its system software using Garmin WebUpdater.

A hard reset (or Clear All User Data) has been known to resolve unit quirks and strange behavior. It's generally recommended to perform it after a firmware update but is not required by any means. However, if you're seeing quirks and strange behavior with your unit after the firmware update, it is a good idea to do a hard reset of the unit.

Backup and Restoration Procedure for Favorites:

The Hard Reset procedure has been known to delete your Favorites, so back them up beforehand.

  1. From the Nuvi drive, copy '/Garmin/GPX/current.gpx' to a backup location on your computer.
  2. After the hard reset, copy your backed up 'current.gpx' from your computer back to the '/Garmin/GPX/' folder on the Nuvi, but be sure to rename it 'temp.gpx'.
  3. On the next power cycle, the Favorites will be read from 'temp.gpx' into the non-user accessible memory area on the Nuvi where they are actually stored.
Perform the Hard Reset:

*Note that this will clear all user selected settings on the unit

  1. Power the unit off.
  2. Remove the battery and wait several minutes.
  3. Install the battery.
  4. Press and hold (and continue to hold) the bottom-right corner of the screen while powering the unit on.
  5. Continue to hold the screen until the "Do you want to erase all user data?" prompt appears.
  6. Press "yes" and the unit will reboot. This resets all your location settings and user preferences.

If possible after the hard reset, let the unit sit outdoors in the open for about 30 minutes or so to let the unit re-acquire the satellite almanac data.


You have now performed a hard reset of your Garmin Nuvi 1200 series GPS unit.

I hope that helps.

External antenna - Garmin 25MCX low profile remote GPS antenna

I have been experiencing the same problem many have been having with the Nuvi 6xx and 3xx series giving an error message “Lost satellite reception”.

My problem started mid April 2008 and got progressively worse. I would use my GPS on weekends and it would work perfectly for the first 10 – 30 minutes and then would loose satellite reception, rendering it useless.

I bought my Nuvi 660 when it first came out in October 2006 for just under $700 and is now out of the 1 year warrantee.
I called Garmin Technical Support and we checked my Software version (4.40) and more importantly my GPS SW version (3.00). According to the tech I had on the phone, the GPS SW version was more important then the Software version. It was in fact already updated to 3.00, I did master reset, after master reset, but regardless, nothing helped.

I contemplated what I should do.
Return mine and get a refurbished unit from Garmin for $225 with only a 90 day warrantee?
Buy a new Nuvi 660 for around $300
Buy a new Nuvi 2xx series with fewer features for $200 to $275.
Buy a Megellian GPS?

I read through this forum and came across one person that was told by Garmin “that they are aware of an issue with some Nuvis involving the failure of a diode in the unit that senses whether or not an external antenna is connected.” Apparently this diode failure is caused from the high heat these units experience from being left in a hot car for long periods of time. This would explain why mine would work in the beginning and then die.

So my thinking was, if the diode “thinks” there is an external antenna attached when it isn’t, what would happen if I “did” connect an external antenna?

Garmin recommends the Garmin GA 25MCX low profile remote GPS antenna for the Nuvi 660 and costs $31.49 (not sure about additional costs for tax and shipping)

So I purchased the NEW antenna from a seller on eBay for $25.90 total and IT WORK FLAWLESSLY.

Just to make sure it really was the new external antenna that was working and not the unit coming back to life, I started my 3 hour journey with the external antenna NOT connected. As usual it lost satellite reception in about 15 minutes. I plugged in the GA 25MCX and it immediately connected to the satellites and never lost them.

I repeated the same process coming home and once again, I connecting the external antenna after the unit reported loosing satellite reception, and it worked perfectly.

Conclusion: if your unit is experiencing loosing satellite reception, and is under warrantee, return it ASAP. If it’s out of warrantee, get an external antenna. There are other manufactures of external antennas and all should work as long as it has an MCX connector.

Side Note: This external antenna also worked perfectly on a friend’s Nuvi 350 with the same problem.

I wanted to share this with everyone because I’ve been racking my brain for months over this. I hope this helps.

Aquiring 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.

My Garmin has stopped finding destinations - just says "Searching for Satellite)+


I had the same problem with my Nuvi 310. Found a solution in here that works. Here's a copy of the advice.....note you will need to get in the car and set it for a destination and go. 5-10 mins later the Garmin Nuvi will lose the satellites, but don't adjust it it, leave it on and keep going. Eventually after about an hour it will right itself, pick up the satellites and evrything will be back to normal.

Here's the advice:

I experienced the same problem about acquiring satellite signal even when it's a clear sunny day. After 30 mintues, it was still searching!
The unit appeared to have "stuck" in this acquiring mode. The following worked for me:
1) open the GPS antenna
2) press the bottom left screen while holding the power button to turn the unit on
3) enter maintenace mode
4) select diagnostics
5) clear error report, do NOT clear any user data
6) restart unit the usual way

My GPS 350 was able to acquire satellite signal in less than 1 minute after the above steps were taken.
