Hello, I have a bypassed AVIC N1 in my wife's Tahoe and the memory navigation quit working. When we pulled the 70 West DVD out of my AVIC D2 in my truck put in the Tahoe, it would reboot and the Pioneer logo would come up and then it would say it was switching to memory mode and it may take up to 30 seconds. However, there is where is froze up everytime. The only way to remove would be to kill the power and hold eject on startup. Any ideas anyone?

Here is an idea, maybe if you re program the unit

but first take the antenna for your radio outside of your car

unscrew it

use it in a fencing match against a world class fencer in mexico

come back to the states and see if that works
