Tomtom 3 and Seidio GR300

After buying an incompatible 2nd hand kit for my X50v, I swapped it with the seller for a cradle & GPS (Seidio). Cradle seems pretty good, with speaker and all, but the GPS receiver appears to be total crap unfortunately. At first I set it to sirf@4800 and it picked up a signal almost straight away, just seemed a bit slow at updating position/speed, but was picking up 7 satellites and all was well.

Then I got to my location (Skipton, England, in the hills a bit but signal was good till I got there) and that was it - no satellites, no signals, just steady flashing green light, sometimes it would turn *almost* solid green but wouldn't connect again. Tried just about all of the different settings in Sirf and most of the nmea settings from 4800 up too, all the way back home (where I'd previously got a signal Sad

) Tried dangling it out the window of the car, still nothing. Am I choosing the right settings for this thing, or...

Are we being invaded by aliens who've destroyed all our satellites?
:x
Is this the end of life as we know it? 8O

Anyone have any suggestions what to do with this stuff?

If the suggestions are:

a) Bin it
b) Stick it on ebay
c) use it as a paperweight
d) Use the green flashing Led as a bling addition to my car
e) Test its' durability with a hammer

Then don't bother, I thought of those Smile

Have also ordered another GPS kit off ebay for one last try at this thing.

*sigh* It was all working rather well (if somewhat slowly) for a while as well.

Here's hoping the new kit works better than this stuff...

Why on earth do you have to set it to SiRF ? Set it to NMEA 4800 - that should be much more stable.

I'll try it again today when I head to work. nmea 4800 and com port 1. Any other settings I should try, or is that it?

Also the baud rate on the gps - is 4800 the only one that works in the UK? What's the benefits of connecting at a faster speed? Better updates?

Thanks for any help/advice - only had this stuff a day and trying to figure it out, so been scouring messages in the forum for info and found v helpful so far.

Cheers

Paul

4800 is the standard baud rate that will make sure all NMEA sequences get delivered in time (within the 1 Hz update interval).

You can use higher baud rates (Bluetooth receivers are auto sensing but prefer 38400) but all they do is allow your machine to wait faster.

Serial receivers are normally locked to 4800.
