I've just purchased a FM mount for my 910, Has anyone found the best frequency area for this to be tuned into for speech clarity Question

The frequency to use will depend upon your location as it needs to be a frequency devoid of any other transmissions - try a channel search scan on your car tuner and pick a frequency in the middle between two adjacent channels i.e.
Radio tunes to 94,6 and music is heard
Radio tunes to 95,6 and music is heard
tune the TomTom to 95,1 AND the car radio should pick it up.

Using the FM unit in and around London it is difficult to find a free frequency but elsewhere it is fine - Mike

Is the FM transmitter good enough to have it tuned to your normal radio station, so that the TT speaks over the top of it?

Cheers
Paul

Not a chance of that working Paul, the transmitter has to conform with the UK rules pertaining to radio transmissions and as such it has a very very low power output. I find when driving distance I sometimes have to re-tune the device and the radio to avoid the radio station bleeding over the FM Mount - Mike

I find 87.9 is quite good, have travelled up and down the UK on that frequency and only had a few problems.

Blue skies thinking here....

I'm surprised no-one has built an FM transmitter especially for sat-navs that includes the RDS "traffic" flag. This would mean you could listen to another station but the radio would re-tune to the sat-nav channel whenever an instruction was issued.
It would probably have to be made by the sat-nav manufacturer, and integrated with the unit somehow, otherwise the delay might be too long and you'd miss a short instruction, but I'm sure that it could be done fairly easily.

Have I just blown another millionare-making idea? Laughing
