There is no evidence of any sats beig located when looking at the sat data screen. There are no errors in the error log screens. The problem was at first intermittent and then came hard on. Occurred whilst driving with no screen changes at the time. All other aspects of the GPS are working ok. I have updated vith latest update ( 4.7, gps 3.0) but it didn help. Device Nuvi 660 FM.

Has yours been updated recently? I updated mine, (about a year ago), on the website and it wiped all the map data.
I think some of the more recent software update versions have caused problems for certain sat nav models.
Try logging onto the Garmin website, connect you sat nav to you computer and check it has the current software updates. Older models sometimes need to be reset to an previous version of the software to work correctly. To do this you might have to contact Garmin directly by Email to get them to send you the correct software version.
Hope this helps.

report to your GPS manufacturer using details such as
brand
model
make
version
serial number
map version
date
location in X,Y coordinates
perhaps pic of a popular place superimposed with your GPS

the sat nav plug is connecting the data link prong so thinks its connected to a pc. try another power cable.

Open Run window by pressing the Windows logo key+R key together.
Then, type "msconfig" in the run window.
Then, click on startup tab.
Click to uncheck the VAIO Survey option. Click on apply and OK.

Stop the Oasis2.exe services.

Check to see if the cover arm broke off or has missed the lever that makes it operate when you drop the cover down if this does not do it Let me know I will see if I can find anything else but that's all I can think of at the moment, get back to me if that does not fix it and I will see what I can find for you, do the simple first. Thanks for using fix-ya

Hi I will be more than glad to assist you in this concern. First press the power button on the front panel of the receiver for 10secs. once you press it the receiver will turn off and it should turn on by itself, once it turns on by itself you will see attention 015, press the menu button on the upper left of the remote, once you see the menu button press 6, 1, 1 on the remote and it should show on the screen point dish, select on check switch, once u are on the installation summary screen, select on test and it should do a test of 1 of 3 or it depends on your sat orbital location that u have.. once its done, it will show the installation summary screen and you should see sat input 1 & 2 with port1 up to 2 or 3 depends on your sat orbital location, all the trans on the sat 119, 110 or 129 if you have should be ok and green. once you see that all ok, select done on the screen, and it will be back to point dish, select done again, and then cancel all the way out of the menu, it should show on the screen attention 015, let it finish until it download the programming guide, once its done it should show a tv pic. press the dvr button and access your recorded event, it should play the dvr event. if the problem still exist, unplug the power of the dvr from the power outlet for 1 minunte then plug it back again and it should acquire the sat signal and download the programming guide, once it shows a pic. press again the dvr button and access the recorded event. it should play the recorded event, just incase the problem still exist, check what will be the exact error msg, write it down in a piece of paper and please feel free to get in touch or you can call on 1-800-333-3474..in order to for the dish tech support replace the receiver, this is a dvr lost of function.

it sounds like a data corruption and it thinks it has not booted properly which it hasnt!
needs a reinstall

low battery level is one reason for poor connection to satellites. However your problem may be a faulty SIIRF chip. Now I have to say that connectinhg the unit prior to starting the engine can damage the chip so refrain fromn doing this in any future GPS operation. The reapair for bad chip if not under warranty is arms and legs cost

go to Marbella Australia ( Marbella Altina) website to look at two units in products area A 8010 and A860 I think both are excellent units well supportede and maps are Polstar for whatever country you need. use the contact button to make an enquiry or go to the order button you will be contacted back within hours, great service!

Garmin are OK but jolly expensive to repair and upgrade and have lousy backup service

If you decide to buy a relaible GPS get an ALTINA they make the boards for most GPS units on the market Except tom Tom and Mio which are cheap and nasty there are so many faults on those brands on this forum i am surprised they are still in business.

I have a feeling that this has something to do with software on the hard drive. Either the software needs to be restored on it or it could have crashed. A Konica/Minolta dealer in your area should be contacted to send a technician out to look at the situation.

ok I fixed it....took out the sat nav and cleaned the lens with a cotton bud..WORKS!!!
