Question about Garmin Nuvi 660 GPS Receiver

1 Answer

Poor satellite reception

My Garmin takes a while to get reception, works for about 10 minutes and looses reception. Sometimes it regains it after a long wait but not always.  This happens regardless of where I am.

Re: poor satellite reception

The cheap way to fix it is to make an extended antenna

if you look in the back youll see a gold circle that is made to add an external antenna. now get some foil twist a small strand and push it in the back of the nuvi untill it hits the gold ring. just add some scotch tape to hold it and it should be good

First time using my garmin 205W and it only holds satelite service for about 10 minutes

I recommend you replace the firmware and system software using webupdate. Updates in the Nuvi 205 firmware has increased its satellite reception and accuracy.

I hope that helps.

Frequently loses satellites.

I can help you fix the satellite problem with your Garmin Nuvi 265WT.

Poor satellite reception, loosing satellites, and taking a long time to acquire satellites are issues that have been addressed by Nuvi 265WT firmware updates.

There are three steps to take to get your Nuvi 265WT running better than new:

  1. Back up your Favorites.
  2. Perform a Hard Reset.
  3. Download and then run Garmin 265WT WebUpdater to replace its firmware / system software.

I hope that helps.

When turn on always says poor satellite reception,

Hi Carlos,

You are receiving that message because the GPS is unable to acquire satellites. Satellite reception can be limited due to one or more of the follow reasons: Poor view of the sky, GPS antenna not deployed, used indoors or other internal problems.

Try taking the device outside in full view of the sky - preferably with little or no tree cover, tall buildings, etc. and allow up to 2 minutes to acquire satellites.

If unable to acquire, it may require return to Garmin for repair. Contact Garmin based on your location and product below:

Lost satellite reception

I have the same problem, and so far the only solution is patience. If you are in a cutting, or between tall buildings, and the satellites are low down on the horizon, then it seems reasonable that reception will be between poor and zero. But in wide open spaces mine too sometimes loses the signal. Hang in there, and contact is restored.

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.

Garmin gps, novi

What do you see if you use it in the open air? Same thing?
Some cars have a metal coating on the windows that works as a sun block, usually french cars. In these cars satellite reception is poor and this can be a reason for bad reception. Sometimes these problems also occur when a cell phone is too close to the gps. The gps does need line of sight to the sky to get a good signal, usually stuck to the windshield is sufficient.

Garmin eTrex Legend

Do the following: 1 - Make sure you have fresh batteries in the unit and turn the unit on. 2 - Check the GPS date and Time. On the Main Menu at the bottom of the screen, you can see a date and time. If the date and time are not current, then the clock is your problem. You will have to wait for the almanac information to be updated. Details are below in a later section. 3 - Make sure your GPS is in the Normal Mode and not a demo mode. Verify other systems settings. Go to the main menu and click on Setup icon. From the Setup screen, access the System screen icon. Verify the following settings: GPS: normal WAAS: Enabled Language: English or your choice. Battery: Set according to your battery types. 4 - Check your GPSs Version Software. Go to the main menu and click on Setup icon. From the Setup screen, access the System screen icon. From the System screen, access the sub-menu icon in the upper right bar. Select "Software Version" from the list. Verify the actual software version for me. The latest version available for the eTrex Legend is version 3.90 dated March 2008. Update the unit using this latest software and using Garmin's Webupdater. If that won't work, use the following download page to access the latest software updates per units. 5 - Resetting your GPS clock and almanac information Next you may need to acclimate your unit to a new date and time (almanac information). If you had your unit off and without batteries for over a month since you last accessed satellites, then your clock and almanac information may be incorrect. Even Garmin acknowledges this problem after software updates and the problem with accessing satellites. They state: "unit data including alamanac information may be incorrect or cleared. Back up all user data before upgrading. After installation is complete, place unit with a clear view of the sky for 15-30 minutes to re-acquire almanac data. " I know of no way to reset the clock using the GPS menus. All I can suggest is that you do the following: A - turn the unit on and wait 5 minutes or so for the "Poor Satellite Reception" screen to appear. See page 7 of the owner's manual. B - Set the "new location" to your area using the map when the "poor satellite reception screen" appears. Be sure to use the "map" option and not the "automatic". C - Set the GPS outside with a clear view of the sky. Check on it every 10 minutes. When the "Poor Satellite Reception" screen appears again, then click on "Restart Search". The "Restart Search" option is used when the date provided in the GPS is not today's date. (See page 7 of the Owner's manual for an example) Legend Owners Manual: D - Once the GPS can track 4 satellites, then the clock should reset and you should be fine. This process could take up to an hour. I have had this problem with my eTrex Vista and eTrex Legend (both backup GPSs) and resolved it by having the clock reset. In fact, I just tried my eTrex Legend today after not using it for many months and storing it without batteries and it had this same problem. I followed the steps above to fix the problem. This took about 35 minutes.
