BT GPS - Baud Rate?

[chipfork]

I've just been reinstalling TTNAV5 on my PDA. I'm using a BT Holux GPSlim 236 GPS, previously I'm sure I had this configured using "Other Cable NMEA GPS" on the relevant BT Serial Port, set to a baud rate of 4800.

Does the baud rate setting really make a difference, if I set it higher will the communication speed improve? I presume as long as the throughput can keep up with visual map updates then that's fine, so 4800 should be fast enough I guess. I've occasionally noticed a lag, if I'm on a roundabout I'll be turning off whilst TomTom shows me circling, not sure if that's related.

Any recommendations?

Many thanks.

The correct speed for the 236 is 38400 BAUD, you might have had it configured as "Other cabled NMEA GPS" but it should also work fine set up as "Other Bluetooth GPS", if you use this option you don't get asked for the speed.
Even at 4800 this is sufficiently fast enough for the data that is being transmitted once per second to make the trip to your device, The more usual culprit for slowing down the map is having loads of POI enabled, disable them and use the warn when near POI instead this doesn't burden the PDA in the same way - Mike

Many thanks, through luck rather than judgement I set it to 38400 and it seems to remember that setting each time I hit "configure".

I have got lots of POI's enabled, I'll certainly change that configuration around, thanks for the tip, much appreciated.
