Used my L-Nav without problems in July.

No audio vario sound from my L-Nav. Makes a short, soft "choo" when
turned on, then nada.

Any ideas or advice?

Roy;

I had this problem last year. I hooked up a speaker to the 'external
speaker' wires on the L-Nav and got through the season. Mine turned
out to be the speaker itself. It arrived at Cambridge on a Monday and
it was back on my step on Friday with a new speaker and updated
firmware! Not bad service.
