I decided to have mine installed also, rather than doing it myself. Total cost for me was just under $300, and the install itself took maybe an hour. What was installed was:
- Compustar FT-DC3-LC remote start module
- ADS-THR-MA3 iDataLink T-Harness
The remote start works with the factory keyfobs. I chose not to add on any extended range remotes. I also had the remote start sequence changed to "Lock>Unlock>Lock" so no honking of the horn for multiple Lock button presses in a row.
A few observations on the functionality:
- Secure takeover happens once you enter the car and press the brake pedal. At that time, the Infotainment system boots up and the automatic climate controls kick in (versus dash fan running high speed after remote start and before takeover)
- Following remote start, if the keyfob is NOT in the vehicle and the brake pedal is pressed the engine shuts off
- The Auto headlights are disabled during remote start. So, even if it's dark out and I remote start the car, only the parking lights come on until the brake pedal is pressed
I had remote start on my past two cars, and that was one thing I was missing on the Mazda6... until now.
