Question about Garmin Nuvi 660 GPS Receiver

1 Answer

Garmin Nuvi 660 map is lagging behind position

The map is very accurate when stationary but when I move away it becomes almost sluggish it seems. Like its a few seconds behind. I will pass over an intersection and see it approaching still on the map. The map Im using is loaded onto a memory card. Its the upgrade 2010 map for South Africa. I have tried numerous memory cards to see if it was slow tranfer speeds, I have tried the basic street maps and the topo maps, I have tried NT and NONNT maps to see if its the compression that causing a problem. Everything acts the same. I never had this issue with the 2008 maps. I have tried maps on two different DVDs just to make sure it wasnt a dodgy DVD with dodgy maps. Now I cant revert to 2008 as I overwrote the files. :-(

Could it be something that I can reset in the device?

Many thanks

    Hey Xenomorf43

    Thank you very much for your reply! I have looked at everything you mentioned on the device and I still can't see an obvious issue. All that was showing was a custom poi of speed camera alerts. I removed that and still the same issue. I will take a look at the mapsource and mapinstall in the morning and see if there is a way of uploading different screen sizes. I don't recall seeing anything about screen sizes. It was simply load map, unlock map, select all the required areas and transfer to device. I found my 2009 DVD so I loaded that on various options (maps, map typed, sd cards) and still it's doing exactly the same thing.
    If I can't get it sorted out tomorrow then I will let the issue rest for a while as I'm away for 3 weeks

    Thanks again. I appreciate your help!

    Regards

Sounds more like a problem for garmin, but here are a couple of maybe suggestions. Go into the settings menu and see what is displayed IE rest areas, gas stations, restaurants, things like that, the more "things" you get out of the display the faster the units response time will be, it also sounds like you might have loaded the wrong screen size onto the unit when you upgraded the software however that i can't say one way or the other on. Final note the more things that the display has to show you the slower the unit is. Hope this helps

Can u tell me how to download free up dated maps for my garmin nuvi 660 thanks vicki


Hi Vicki, unless your nuvi was first activated and acquired satellite lock in the last 60 days (unlikely as yours was discontinued a long while ago) then you cannot get free map updates, sorry.

For models activated within the last 60 days Garmin offer a free update to the latest maps if the maps already on the product when it was purchased are an older version. After that, all updats must be paid for.

You simply won't find free map updates legally. Accurate maps cost a fortune to produce and update so nobody gives them away, even the few illegal downloads tend not to work and if they do work are likely to be out of date anyway.

The way that Garmin price their map updates, it's often better to simply buy a new Garmin with the maps pre-installed, although I appreciate that's not the answer you hoped for. If you do buy Garmin updates then you can either go for a one-off update, or for additional cost can buy a lifetime update, but it's limited to the lifetime of the device which is only designed to last three years anyway so may be poor value if you buy the lifetime update and your machine then dies of wear or old age.

660, hangs up totally after ca. 40mins use


Hi Martin,

It sounds like a corrupted firmware update. Please go to this site:

http://gpsinformation.org/perry/nuvi/

I believe the latest firmware version for a 660 is v4.7. You can try reflashing the firmware with v4.7 or trying an earlier version. Let me know if this resolves your issue.

Also, the Nuvi can lag if you have large picture files on an inserted SD card.

I need a registration code for garmin nuvi 660


You need to register your product first on www.garmin.com. The product code needed is located behind your sat nav on the barcode sticker. Once you are asked to enter this on new maps or updates etc, it will tell you if any are available. Most you have to but.

If a GPS gets a factory reset, powered off for months, or powered up again in a different country, it will eventually scan the sky for any satellite it can find, and then download a new almanac and ephemeris - which can take up to 12 minutes after it finds the first satellite. This is best done stationary, to minimize the doppler effect until a fix is acquired.

2009 map update not loading


Fixed. Called Garmin. It seems that version 4.90 FW on the Nuvi 350 (which came shipped on my 350) has a bug where it cannot communicate with the Garmin software either to update maps or update FW. Tech from Garmin e-mailed me a patch that I copied into the Garmin folder on the Nuvi itself, via USB and Windows Explorer. I then rebooted it; the patch installed itself which then allowed the unit to communicate with the map upgrade software and all is well. 2009 map update is now installed and the Nuvi is working fine again. Haven't tried upgrading to newer FW yet; will probably leave well enough alone.

Map fro Garmin


As far as I know you can only buy maps from Garmin, or a Garmin retailer.  The 660 should have all the maps for North America already loaded in it.

You can purchase Points of Interest (POI) databases from a variety of sources.  Just google POI.  These are not maps but they are adresses for points of interest such as restaurants, special services, and even speed trap cameras.
