To all Fortuna GPS +TomTom3 users

I am finding it very difficult to to get the Fortuna GPS to lock on to staelites, bluetooth bonding fine, (I have the lates rom) but the fortuna never locks on, even though it sees 6-7 satelites. Could this be the London Weather (Heavy grey coverage) Has anybody else had this and is there a GPS testing tool besides tomtom gps 3.03 in case it is a software issue?

Living in London, it onlyh works in Xtract mode, never in the ST, does anyone else have this problem?

It could be your windscreen, have you tried it outdoors. I have a fortuna gpsmart and it is brilliant at locking on to sats. Some windscreens have an ingredient that blocks signals, try it in the back of the car instead of the front too. I have driven in London and the only time I lost lock was when I mistakenly drove into a bus terminus which had a roof.

I walk around town for now. COuld that be it? lack of motion?

Lack of motion shouldnt affect it, but accuracy is increased if moving as far as I know.

How long are you giving it to lock? If the batteries die I think it resets and has to download a whole new almanac, if you still arent getting a signal after an hour then it may be a faulty unit, I had a faulty haicom gps that displayed the same problem.

On Xtract it's fast, on the other mode, barely ever, this is the second one I get w/ the same problem from Vivo/ off ebay...Beginning to wonder. Is this a GPS issue or a TomTom one? WHat would you guys guess?

I tried to use this but it only offers com ports 1-4, and I was unable or could get the Fortuna to work with these. right now, it only works on three ports, either :

-com 5
-BT Port
-the Fortuna Clip On Port

Yesterday, it worked very well on ST mode, then i turned it off and came back an hour later, it couldn't get a fix again. This morning it got a fix in 5mins. Could this be London weather???? Or thdo these things reset in some way that causes them to need to relaod an 'Almanac'???
