Hello I recently installed a 130bt and am having people complain about a high pitched noise when speaking with me through the radio. I cant really figure out what is causing this feedback or what my fix it any ideas would be greatly apprectiated. Thanks

Hi I was wondering if this is just the map update or a full system upgrade to the 140bh, and if it is a full system upgrade will it allow app radio to work with android on my 130bt
