Question about GPS Devices

My Garmin Nuvi was working fine, but then lost satellite reception during use. Since then it has been unable to locate any satellites and therefore find a GPS signal. Any ideas?

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. "

    Have you tried using an external antenna? There is a known issue with the Nuvi antennas where a part has failed causing the antenna to only accept signals from the external antenna jack. I have verified this issue on several Nuvi's. Try inserting a piece of wire, a few feet long (one strand) with no shield into the jack and sit back and see if it finds the satellites. I am working on a fix for this problem.

Unable to get satellite reception


Make sure you are not moving and that you are on an open field with minimal aerial hindrances. It takes time for the GPS unit to acquire satellite signal and makes it difficult to acquire when you are moving so make sure you stop at an open are till it syncs with at least 3 satellites.

hope this 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.

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.
