Finally got round to fitting my genuine audi handsfree. All was good when i tested 2 weeks ago. Plugged it all in properly yesterday . And could not see it for ages.. Messed around took ou and back in and then searched when ignition was off and it was found.. Hooked up my wifes phone then mine switching between the two no problems. Drove to work this morning turned on my Bluetooth and nothing cant see it again. what gives any pointers of where to start..
