Hello everyone. I'm a proud new owner of an Electric Blue CX7 GT with Technology Package and Preferred Eqpt. I didn't get the Remote Start and Sirius add-on. I am not interested with the Sirius but would like to add the remote start. Should I opt for the OEM Mazda Remote Start or should I go with aftermarkets? I already had a quote for an aftermarket remote start with alarm for $400 from a Certified Mazda Installer.
