Yes, I read the manual. And it states that I can have multiple cell phones connected via Bluetooth on the Bolt's system. Except, when I try to activate one of my several phones, it disconnects the phone that was working on the system.
Every Bluetooth device I've ever used kicks off the currently paired and connected source as soon as I attempt to connect a different source (that was previously paired). Why would the Bolt be any different?
Are you certain that the manual doesn't say "paired", rather than "connected"?
