Got this email from bel...its looking promising....watch this space!!
You might have the impression over the last few months that we are ignoring you and others about the audio for the STi. None of your e-mails have been deleted and they are on top of our mail box at all times as a reminder. You were informed we are working on this and will contact you as soon as we have something solid to report. our engineering department has been working on an alternate software to give customers an option for the audio ramp. Past Bel detectors have also used this audio programming and many customers actually like the way it is.
However, for those that would prefer a more "linear" audio style, we are testing the new code now. I expect to get confirmation within two weeks. If there are no concerns we will contact you again (hopefully in that two week time frame) and ask for you to send in your STi Driver.
There will be no charge for you and any other STi owner that is interested in this change.
I don't have any info on the STi-R and I am not sure that will be included in this code revision.
Hang in there. We are a small company and we are peddling as fast as we can!
