 Posted: Fri Jul 09, 2010 9:05 pm Post subject: GPS Quickfix not quick anymore? |
 |
|
| I have Tomtom 530 and it's taking around 3 mins to pick up a gps signal even after downloading the latest quickfix update. It was fine until a couple of months back but is really slow now for some reason. Does anyone have solution to this. Thanks. |

Have a look on the unit and move the contents of the "ephem" folder to your PC.
Then, with a good battery charge, take the unit outside and let it have a good clear view of the sky and switch on. It'll take a while to get a signal but after that it'll only be a few seconds. Leave QuickFix for a week or so and download it again, if you want to.
I get various problems with the signal on my 740 which i put down to QuickFix. Without it the unit takes ~20-30 seconds to get a fix. With QuickFix it takes 2-3 seconds. However occassionally i get an update that casues the unit to loose position randomly and i can be doing 40 mph on a local A road and the unit shows me 5 miles away doing 125 mph across fields. Eventually a QuickFix update does seem to fix this.
I only update QuickFix once a month or so now... |

On the X40 & X50 I think the quickfix is also automatically downloaded via Live Services as well as Home as I once removed it and it reappeared when I had not connected to Home.
I am sure there used to be an icon on the 940 menu to manually update Quickfix but I cannot find it anymore, although it is still there on the 530.

I connect my TT once a week and get qf as one of the downloads. Average time to signal acquisition is about 45 seconds, though sometimes it is double that. It seems to make no difference as to how recently I have used my TT, I can turn on the next morning and it takes 90 secs, or after 2/3 days it can take 30 seconds.

My 930 is much the same with taking a long time to get a fix.
It use to take just a few seconds.
I think in my case this is due to the battery, which is not holding a charge, and I have ordered a new battery which hopefully should resolve the problem

I have cleared the files, and got a fix quite fast when I took it outside, but the battery died soon after.
I will try it in the car tomorrow, as it's normally the following day that it takes a while to lock the satellites.
My battery only lasts 30 seconds at best, but have ordered another which hopefully delivered next week.
