I installed map 915 UK& Ireland, Navcore 9.510 on my Go 740 Live.

I tried many FM stations but none worked!

Anyone knows how to solve this problem?

I don't know what exactly you are trying, but you can only receive on the frequency you set up on the TT.
And it obviously can only work if the output is set to FM as well...

I set the output to FM and both my car radio and the TT to same frequency. However, I cannot receive any music sound from my TT on my car radio!

Do you hear the sound from the TT speaker instead?
If so you might want to tell your TT to use the FM tramsmitter for the output.

You want classic fm for tmc
