Keeps changing every 2 seconds dropping down and up. The connectors seems fine.

I am still waiting for my GPS device to arrive in mail.

There is a NAV equipped 2000 LS in my salvage yard nearby me if you need anything, It looks like its complete with only 151k too.

I have a sad news, We are back to beginning again it seems. So I thought 1/2 issue were fixed. My bootup speed was 3 seconds and faster. But what happened is recently I had this code P0172 which is "System too rich (Bank 1)" and I figured It might be the MAF sensor so I took out Filter. Alot of dirt and bugs. Cleaned it and cleaned the MAF sensor too. Fuel mileage has increased and been like 3-5 days since the error code hasn't come again. But when I removed the MAF sensor and put it back. I also did remove the Neg terminal of battery and put it back. What I noticed today is my system took over 10 seconds to boot everytime and the MAP/Navi options no longer works. Gives error "CHECK HARD DISK". This was the same error I had with my old one with slow boot but replacing with eBay one fixed the problem but I think It's back again. What could be the problem with slow bootup? Could it be that the eBay Hard Disk is dead as well? But do note, Climate, Audio, Trip Info and all others work. Now everytime I start the car I have to wait like 10-14 seconds for this to bootup. I don't know how to fix this now. Please tell me.
