Hey guys and girls, I'm having a few problems with my aftermarket radio install. I've got every wire hooked up correctly, and the radio works. But the funny thing is that if the antenna is hooked up in the back off the radio, the radio will not turn on with the switch, and it'll loose all memory when I cut the switch off. If I unplug the antenna, the radio will keep memory, and it will cut on with the switch on every time. What could be the culprit? Sorry for my ignorance, this is my wifes car, I know nothing about it, I'm a Supra guy. Thanks in advance.
