i bought an upgrade disc off ebay and it seems as the upgrade worked new map of the east coast but for some reason i can use the poi nor the phone options their just grayed out? i have the 90 conected to a avh7500. i am able to use the map on the screen and able to get it to route. so i dont think that i need something other than grounding out the green wire. sorry for such a long thread for my first post

Did you ground the parking brake wire on the nav and the deck?

yea the unit was working in the before the upgrade. everything works except the POI and phone number search.
