I'm getting a really cheap STI-R plus that I'm going to install in my wife's vehicle, only thing it's missing is the external speaker. For any of you that have this unit, is the external speaker required? I know some of the CI units have speakers right in the control module and the external speaker is only if you want it louder, wasn't sure if that was the case with the STI-R plus.

Speakers are only built into the interface of Maxci360/8500ci. All of the 9500ci and STir (Plus) require an external speaker. I have a used one for $20 if you want it or mendelsons has them new for $39~
