I have been very impressed with my latest acquisition, (a 2014 RRS SDV8 4.4 Autobiography), and I have enjoyed several weeks of troublefree motoring and really enjoying my return to the marque.

I have noted two issues, however, and both being intermittent.

The first issue is an intermittent audio 'booming' that is most sensitive around the voice frequencies and I believe that it is audio feedback where the audio from the radio, (I haven't tried any other audio sources), feeds back to the amplifier, (presumably via the 'Voice' microphone), resulting in an unpleasant booming sound.

I can also get the booming to start by speaking loudly in the car - hence my noting that it is most sensitive to the frequency of the human voice!

I have worked my way through the various menus and thought I had found a setting that would resolve the problem, (there is a three way setting labelled 'Voice Feedback - low, medium and off), but setting this to 'off' does not resolve the issue.

I have searched both the Internet and this site, (using both 'boom' and 'feedback'), but I have found no other articles about this particular issue and wondered if anybody else has experienced this rather bizarre issue?

My second issue is, hopefully, a little more logical to resolve - intermittent loss of GPS signal and I am planning to try and external GPS antenna to check whether I have a problem with the Shark Fin GPS antenna and/or the cable.

I have noted various topics relating to the GPS antenna, (on this forum), and will be checking the antenna as soon as I have a little free time!

Regards,

Martin.
