Maestro SW not flashing

Post by carstenseth02 »

When I got a new car (2008 Subaru Impreza WRX) it had an aftermarket stereo and a Maestro SW installed. I wanted a different stereo so I installed a new radio (Sony XAV-AX100) I didn't have the cable that came originally with the MSW since it was already installed by previous owner. I bought a ADS-USB cable so I could flash the correct firmware on the MSW.

I plugged it all in and it recognizes the cable and module. I was able to go in and choose the vehicle and the stereo just fine. When I go to flash the module it pops up an error "InvalidCTRException".

I am wondering what is going on or what I am doing wrong.

the Maestro units don't use the ADS-USB cable, that is for our remote start modules. We use a standard USB to mini-USB like is used with older digital cameras and such. If you look for a cable to use make sure that the cable is designed to pass data and not just for charging only.
