A couple of questions which i hope someone can help with?

Hi all

My testing of my sysonchip compact flash has not been as great as first thought? It appears that i am suffering a little lag with the system eg i'm not getting map updates or speech until i'm right on or past the turning.....which is a real pain in .....?

Can anyone tell me what factors will introduce lag? For example i dont have much free space on my SD card. Will this have any influence? I have a 3rd party task switcher running again will this make much difference? I'm running checkpoint also. I'm looking for POI every 1 seconds.
What about running on battery (as i've not yet purchased an in car power adapter until i'm happy the system is working OK)?

I have tried the system running the generic NMEA 4800 drivers in TomTom3, I have tried the sysonchip compact flash nmea drivers, i have tried the generic sirf drivers all with the same results being a small amount of lag, maybe a couple of seconds and enough to be irritating?

Any ideas or remedies please?

Also what is the difference between NMEA and Sirf??

Just for the record the system is a acer N10 with a sysonchip compact flash receiver running tomtom3, checkpoint & Vbar with 128meg SD card. I'm getting great satelite fixes usually 7 on average and in some case as many as 10 which seems awfully good (i'm not experienced with GPS so this might not be as good as i think?).

I have done an awful thing and re-posted this in the advanced GPS forum. Sorry if this is not the right way to do things but i'm getting no response in the beginers GPS forum? Therefore i'm guessing that's because people trully dont have an answer or the topic maybe of an advanced nature?

any ideas?

Cheers
Darren

...try disabling all your other processes, just leave the SatNav running, and try temporarily dumping some stuff off your Card to your PC to make a little more room - see if it makes any difference.

Do you have avail a differnet SD card to try - the problem sounds like a slow card, get a good quality high speed card - some one at work might have a different card you could try for no cost to prove the point before you spen hard earned cash, but they don't cost too much these days anyway - Mike
