GPS Baud Rate on TomTom5

[pmanson]

Just upgraded to TomTom5 on my pda. I use an HP iPAQ NavSystem 2 GPS jacket.

I've got the GPS baud rate set to 4800 which works but it just seems slow in gaining a connection.

Any suggestions?


Thanks,

I use a royaltek sapphire GPS mouse on my 2210,

I've just checked my settings and thats 4800baud too.

The first time I used it on TomTom 5 it seemed to take a long time to lock on the 3 sats, the second time I used it that week the GPS wouldn't lock on my position while I sat stationary for the route to plan. Then as I set off the GPS locked and the route was planned.

Now it seems to lock on within 30 seconds.

The baud rate won't affect the acquisition times, its the internal chipset and aerial that come into play and the cold/hot standby times massively between them.

NMEA (the underlying protocol) only requires limited bandwidth, as I recall 1200 baud is sufficient usually

Thanks all,

I seem to remember having trouble with TomTom3 picking up a signal in Bournemouth before so its probably that.

What I do remember is that if TomTom3 had a signal and I had to reset the pda (common occurance on my old pda) it would find the signal almost instantly while TomTom5 seems to have to wait a while.

TomTom does seem to run smoothly though once its running

As I recall TomTom3 had the NMEA/Bluetooth directly integrated, so while it worked well, it wouldn't let other Bluetooth devices work (such as phones) or other running applications get hold of the NMEA signal.

TomTom 5 was re-architected (hence no version 4) so I guess the integration is now external, thus helping those who want to use a Bluetooth GPS device as well as a phone for traffic information.

Might be wrong though...
