Trimble Access Installation Manager (TAIM) is now Trimble Installation Manager (TIM). You can now update R8 GNSS receiver firmware using this utility. To install TIM just run TAIM on your computer if currently installed and it will prompt you to update and install TIM. Note the question mark in the lower left hand corner this will take you to the online help.
If you are using a Trimble Tablet, install the Trimble Installation Manager directly onto the Tablet.
