I'm using my Go 920 via Fm Transmitter, but it often looses signal due to other radio signals higher power.
I tried to set a wide range of frequencies but without best results.
Since in the past, with older navcore, before new rules in the fm transmissions, the fm transmitter worked better, I think there is an instruction set in the new navcore that manage the power transmission.
Has anyone an idea to increase a bit the fm power transmission in navcore 9.701 ?
Switching off is because new legislation some years ago. Tranmitting is forbidden when nothing is been send and this happens often when there are no instructions for some time.
Playing a MP3 without music is also my solution to the problem because there is no setting for increasing the volume.
To set the transmission to autostart: First of all create that soundless MP3 (5 seconds duration will do) and place in map with the name MP3. Set playing mp3 to repeat mode. Next set spoken instructions to use FM. Next: Change preferences - Start-up preferences - Start TomTom Jukebox.
Next time when you start your TomTom it will autostart the MP3 and also instructions thru FM transmitter each time.
What do you think about older navcore version had better fm power transmission?
I remember when I bought my Go 920 (about 5 years ago), the fm transmission was better and I had not problems.
I think due to new legislation rules, new navcore keep low the fm transmission's power. For this reason I'm asking about any mod or hack to manipulate that setting.
