    My Tomtom GPS t hinks it's still in Vermont ... it can't find the satellite. We took the Garmin from the other car ... and that one could only get one bar ... then it was good ... and then it lost the satellite too. We're in Connecticut and both have always worked here.

I have being having similar problem as every one else. There is nothing wrong with your Nuvi. Garmin (the company is the problem) they are trying to make you buy a new map--Not Exactly Cheap--Do Hard Reset and solve all the problems.

1) Place a finger (Any finger, middle finger worked for me!) at the left lower corner and turn on the Nuvi unit a message appear saying "Do you really want to start up in maintenance mode?" tap Yes
2) At the Maintenace screen tap clear user data (this will restore to factory condition) and follow the instruction on adjusting your prefered setings.

3) turn it off and Repeat step 1, this time when you get to maintance screen tap on "Clear waypoints" and follow the instruction. Let it sit for about an hour then voila.

SOURCE: my Garmin Nuvi was working

Here is an email received directly from Garmin: I have tried this myself on several units and it worked. I can't gurantee it will work for all cases. In some cases the antenna may be defective. Also, click on the "wrench" symbol, then the "gear" symbol and then "about". Look at the number after the text "GPS S/W:" It should be a number like 2.9 or 3. If its 0.0, then the antenna is not communicating with the main board.

"Thank you for contacting Garmin International, I am happy
to help you with this.

Sometimes the almanac data that your nüvi stores for satellite acquisition becomes corrupted. This causes acquisition to become slow. To correct this we need to perform a master reset. This procedure will erase all user data.

With your nüvi powered off, press and hold the lower left corner of the screen. Next, turn the power on. Continue to hold the screen until it asks if you really want to enter maintenance mode. Next, choose clear user data. The screen will flicker a bit and then start up like it did when it was first turned on. Follow the directions to set time and location. You will have to reacquire satellites by turning on your nüvi with the antenna up outside in full view of the sky. This one time
acquisition may take up to 30 minutes. "

DIY is risky in this situation, besides there is 3 months warranty by Garmin on their interventions I would suggest you get it done by the professionals

This problem is not caused by poor solder joints. It's caused by a defective part. We sent a "marked" defective unit to the repair shop mentioned above and upon its return, disamantled the GPS receiver assembly and made the following evaluation:

1. The shop did NOT replace the defective component causing the initial problem in the 1st place. The defective part was STILL in the circuit.

2. The shop placed a wire jumper between the internal antenna and the external antenna port. This type of modification places a +2.5VDC bias on the internal antenna and essentially shorts the internal antenna to the external antenna (when connected), giving unpredictable results. It also affects the circuit impedance and signal strength. This is not the correct way to resolve this issue.

3. The defective part needs to be replaced with a higher rated part. This type of repair returns the unit to full functionality and allows the unit to properly switch between the internal and external antenna as it was intended to do by design

Comments: I will aso add, as the part deteriorates, it becomes resistive and can eventually short out and shunt the incoming RF signal to ground......EVEN with the jumper procedure performed by the shop mentioned above.

My new Garmin Nuvi 1450 lost satellite signal more than 30 times between Topeka Ks and KCI. Is this normal?


I have the same exact problem. Satellite detection outside of vehicle before starting out was full strength, as soon as you get into vehicle strength drops off to practically nothing. Now start driving and it continually loses satellite reception even on the open road with no hills and a clear day. It was mounted as far into the front windshield as I could get it and still crappy reception. Very disappointing as a cheaper Tom Tom my sister has works flawlessly. Also my daughters HTC desire Z cell phone GPS works flawlessly even from the back seats in the van. Maybe 1450LMT is just junk, and I should look for a refund.

Voice activation capabilities locked and none functioning after driving for 2 hours or so. Satellite reception getting lost even on a sunny day


I can help you reset and fix your Garmin Nuvi 265W.

Erratic behavior and improved satellite reception has been addressed in new system software / firmware update.

There are three steps to take to get your Nuvi 265W running like new:

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

I hope that helps.

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.

Satelite reception lost constantly


Hello sothypaw,

In order to receive satellite signals your GPS receiver must have a clear view of the sky. If you are using the GPS inside of a vehicle the body of the vehicle may shield the unit from receiving these signals.

To minimize this the GPS should be mounted at the lowest place within the automobile that has a clear view of the windshield and side windows. If you continue to have problems then you might consider purchasing an external antenna for use with the GPS.

Even with a properly mounted GPS you may occasionally lose satellite reception due to local terrain (hills, mountains, dense forest etc.) or other obstructions (parking garages, tunnels, etc.) which can block reception.

Best Regards,
Ken

Lost Satellite reception


If its raining, that will cause you to lose satellite reception.

If that is not the problem, then do this: turn off TV & satellite. Wait 5 minutes. Power back on. Most of time this will fix it by itself.

If neither of those do it, unattach your satellite cable from back of satellite box. Power everything off. Wait 5 minutes. Now reattach your satellite cable. Power everything on. It should search for you sat and find it. Let me know if this works.

If none of those work, then I would call the sat company for help.

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.
