TomTom Go 300 Poor Reception....

Hi All

I have just E-mailed TomTom re the Go 300. I have just driven a 4.2 mile journy. TomTom go was unable to get a fix the whole journy I then set up my PDA And tomtom 5 with a tomtom bluetooth reciver (the old one) I had a fix within 1 min. 6 sats, 50 - 78% signal. tomtom go only had up to 30% signal strength and would not get a fix. both units placed in the same position.

I belive the problem is not with the cars we have but a software / hardware problem with the reciver in the Go 300. If tom tom wish to give me an external antena then ok. but i am not going to buy one. Or maby they can fix the fault with a software / firmware patch. If not then They can give me a full Refund.

Who else feels this way?

Regards

Premo

It is quite possible that you TTG300 has a poor GPS reception, but to be absolutely sure do the the following:

- find an open space with clear view of the sky

- reset your TTG with a paperclip

- switch it on and go to the GPS Status screen (the one with 14 grey bars showing satellite numbers and Signal-to-Noise Ratios)

- wait for the unit to get a fix (three or more bars will go blue) and note how long it took to get the fix from the moment you switched it on.

- write down all cominations of the satellite numbers and corresponding SNRs.(satellite number is shown at the bottom of each bar, SNR value is shown on the top of the satellite number)

If you have two or more satellites with SNRs higher than 39, then your unit is OK.

just a thought - you said "placed both units in same place" were they operating at the same time next to each other - I tried this with two identical BT GPS receivers and on another ocasion two wired GPS units, and finally one BT combined with a wired -on each occasion the GPS recievers were unstable failing to lock onto much at all - seperation of the units to both sides of the dash fixed the snag - not too sure why they do this must be some interference they generate - Mike

Mike is absolutely correct - other electronic equipment will interfere with GPS reception because there are a number of components radiating signals at frequencies which when combined or simply multiplied will fall in the GPS frequency range, thus degrading GPS reception.

Hi all,

what hegedusa said about the GPS reception reducing as soon as you put the TT in the car mount is correct. If you put the TT on the page that displays the level of reception then place it on your dashboard, let it get a good reception, then simply place it in the mount you should see all the levels reduce. I don't see why the mount should have this effect.

Tried this several times and can say it DOESN'T make any difference on my unit (Go300)
