Chlh42, please take a picture and send to
support@ibolt.co about your issue with the mount not being tight. We'll take care of it for you immediately. Also, we've been going "round and round" on the "static noise/buzzing" in the aux-out and we are down to less then 1% having any issue. In the past weeks we have consistently recommended anyone contacting us to install a Ground Loop Isolator on the 3.5 jack and so far it seems like this has solved the issue... Here's the one we've been recommending but I'm sure there are other good models too.
Amazon.com : PAC SNI-1/3.5 3.5mm Ground Loop Isolator : Electronics Apparently some cars have insignificant grounding on the 3.5 jack or the power outlet, resulting in feedback. If you order this, please let us know if this solved the issue on your side as well.
