also, in order to use the FAST-9999 do i have to take the radio out???
The only way to know for certain what will fit is to take a measurement of the space available in your Sierra. From there compare the dimensions of the space available to the Tubes.
As for the FAST-9999, this is only for use with the BTAXX100 line and NOT
the BTAXX250D lineup. To make the required connections you do have to access the back of the factory headunit.
