My D-3 Cant remember anything except my home adress

[psychomantis]

When I use the d3 everything works fine, after the RAP goes off the radio cant remember anything. It loses navigation routes, past history, background settings etc. I figured that my car does not have constant power going into the radio, but the only thing it always remembers my home route address. I don't think that would happen if the power was being cut. why is this happening?

Home and Go To and Address Book are stored on some sort of memory that doesn't get lost when you cut power. Sounds like you have the power wires connected wrong

i dont understand what i could have done wrong. yellow power wire goes into the harness. connections are fine. what else could it be?

Maybe you blew fuse,check those also.

I didnt blow a fuse. i used my fluke meter to test voltage. i get a 12v constant always. i tried messing with the car (locking, unlocking, alarm, starting it up etc) and i never lost the 12 volts. weird thing is that sometimes the radio starts up with only the button lights on, and no screen. if i reset the radio it fixes the screen. you would think at this point it is a defective radio.

 

I sent it in (btw pioneer has awesome customer service. fast and very helpful) however they said everything works fine. they only tested the memory for 5 minutes. so they offered to test it for an hour while on lunch break. it still worked. then they offered to try it overnight. still we cant find a problem. Now they are going to send it back to me. any ideas?
