Tomtom Go 300: Signal loss & Map Errors

Could you please do the following when and if you have a time:

- find an open space (such as a middle of a car park) with no tall buildings/trees nearby

-place your TTG on the roof of the car, wait till you get a lock and make a note of the number of the satellites in view and five highest SNR levels

I will give the car park thing ago tomorrow (Sunday) and get back to you, am going to a computer fair so finding a deserted car park should not be a problem.

i hope you can find it
anyway just standing out in the street should indicate if you unit is locking onto the satellites ok...

For info.

on my TTG (not the 300) I normally receieve 5 or 6 satellite signals at above 40 whilst outside our Renault Scenic (athermic windscreen). When I get into the car ALL the levels drop considerablt to less than 20 ! Lock is soon lost.

If you move the TTG to a side window the levels come up to around 30 to 35 and lock is reagained on about 4 or 5 satellites.

I was never very impressed with the signal levels inside the Renault or my Audi A4 (non athermic).

I have bought two TTG external aerial kits. These incorporate a 28 dB gain amplifier in the patch aerial. I have positioned them INSIDE the Reanault under the (RF transparent) rear parcel shelf. The Audi has it under the front dashboard.

I now get full scale (greater then 45) on at least 8 satellites and the TTG behave impecably.

I believe the external antenna/aerial kit gives a very worthwhile improvement to the performance of the TTG especially in built up or wooded areas.

I have to say that I am a bit concerned about locating Tomtom near a side window since having it in the centre of the windscreen I am looking forward as i am driving, so when the signal is lost I can at least see when the next instruction is due i.e. next left,right turn etc which even though signal may be lost the next instruction remains including the distance to that instruction,I will however give it a try.

Can you supply a link to the site or a site where you bought your aerial(s) and any recommendation you have as to which one performs the best.

Many thanks for your input.

I got mine from PDAMods. The link is on the right of this page.

No link on this page to PDA MODS, I had a look @ PDA MODS but was unable to locate aerial.

Sorry OLDBOY

The link is there, silly me forgot to go up the page (DOH!) , where your message was displayed the was just blank space. (Yes there may well be some blank space in my brain)

I look forward to your assessment of the aerial

Went to Tolworth Computer Fair to day,Bloody typical TTG 300 performed brilliantly, very little signal loss.
Why it did is a very good question. I put it on the right hand side of the windscreen instead of in the centre which is my preferred position, this I think confirms what Vauxhall were unable to that my windscreen has indeed go some reflective properties in the glass.
I am still very unhappy with having it next to side window (drivers side) so i guess i will have to invest in an aerial in the very near future.
