Speed Sensor Signal problem and GPS acting strange?

[schandir]

I dont think anyone has come about this problem but my Avic Z2 is causing a strange problem after I did an audio system install. Both of these features were working great before the audio system install. When I go to the Virtual Instrument Panel, I get a no signal even tho the signal wire is connected. And as for the GPS, Its getting proper signal but the GPS does not put me on the proper road I am on and the vehicle directing is also backwards. I just dont understand whats going on..

I would try a "soft reset" and see if it corrects your problem. BTW, it is the small push button at the bottom of the unit (use an ink pen or toothpick). It will wipe out your station presets, eq, and everything else in the memory, but I would give it a shot.

Well i have done the soft reset many times and that did not work. I just pulled the deck back out to see if non of these wires were crimped and sure enough it was not so i put it all back together and now it works!.. Its strange why i didnt work before...?

I partially did 2 wire bypass a few weeks ago.... Just didnt get around to getting ground wire part done

 

 

Z2 was no longer having heat related issues

 

 

then suddenly earlier this week, I turned on car... it lagged coming on... then came on.. I started driving & I didnt get the warning about driving while DVD is playing.... Movie played while driving when I did nothing from my normal routine... Then suddenly at same time, my GPS started flaking... had me 40 miles from where I actually was... then it stopped working all together, says it isnt connected though it i and always has

 

I have a long road trip planned for Friday and desperately need this fixed...
