I just installed a 665 and when I turn the Spyder key to on the GPS powers up. When I turn off the Spyder the accessory ckt powers down 10 seconds later and then the GPS asks if I want to continue on battery power. If I do nothing it shuts down in 30 seconds. My 550 operated the same way until it lost its mind. Is this how yours operates? Where do you have your GPS power hooked up to?
I have the same problem. Wired the 665 cable in place of the factory 660 cable. Sometimes it cycles power every 10-15 seconds. Other times it works fine. I did try putting the 660 back in and the same thing happened. The power cycles are very regular. It acts like a time delay relay. Anyone know what's up with this?
PS. For those that don't know, a 665 will not work with the Cable that Garmin ships with the 660. But the accessory cable that you can purchase works on both the 665 and the 660.
