My dealer installed remote start (Audiovox I think) won't start the radio or lift gate.
I have to put the key in the ignition and press the brake peddle in order for the lift gate to work. Funny thing is, if you press the button on the dash nothing happens - until you put the key in. Learned that the hard way.
From what I understand, you have to hook up separate devices to the remote start. Sure wish those two were hooked up as my Pioneer Navi takes forever to boot up and the ability to open the lifgate would be nice.
