Installing a Compustar DC3 with Compustar Pro R5 remotes and LTE Drone in a 2009 Hummer H2 (Std Key)
I'm struggling a bit with the firmware flash. Do I need all accessories (the Pro R5, Lte Drone...) plugged into DC3 module when flashing?
Thanks
Mule

Resolved. I unplugged everything and flashed. It took several attempts in the setup/flash to get it correct.
Compustar makes good stuff, but doesn't seem to have much love for the DIY garage warrior. Thankful for all the internet threads. With the T-Harness, this thing was unbelievably simply to install. The option setup and firmware flash took longer than the install.
Lock/Unlock, Proximity Unlock, Remote Start all work, and are a huge upgrade to the original 2009 GM equipment.
