advseeker Posted December 18, 2008 Share Posted December 18, 2008 First time poster, be gentle. I have just bought a '99 Pathfinder and today I fitted a Sony head unit using the Nissan factory harness and all is not good. I only have right rear speaker and when I disconnect the aerial lead (the 2 wire one with adapter) the unit powers down (turns off). I have fitted quite a few unit to a variety of vehicles and never had this issue before. Any help would be appreciated Link to comment Share on other sites More sharing options...
Simon Posted December 18, 2008 Share Posted December 18, 2008 Sounds like your ground isn't connected properly, and the unit was grounding through the antenna. Link to comment Share on other sites More sharing options...
edicer2 Posted December 18, 2008 Share Posted December 18, 2008 I almost wounder if you have a higher sound package. I dont know much about the new pathfinders but i have seen on other makes that if you have bose edition sound or a higher package a regula r sound hardness doesnt work its different due to the different sound package the was it it connects to the stock amp. Idk like i said i dont know much about the 96 and up pathfinders but thats something to check it. I had a simular problem with my buddies passat. I just dont know if nissan does that or not.

02silverpathy Posted December 18, 2008 Share Posted December 18, 2008 Exactly Simon...in a nissan you must run a seperate ground. If you used a direct connect harness the grond from the radio goes nowhere...run a ground fromt he radio to the steel housing that the radio & heating unit is held in.

edicer2 Posted December 19, 2008 Share Posted December 19, 2008 if it doesnt have a ground how does the stock one work? mine grounds just fine Link to comment Share on other sites More sharing options...
02silverpathy Posted December 19, 2008 Share Posted December 19, 2008 If I am not mistaken 96+ pathys have a single wire connector that pushes into the back of the OE radio that is a GND wire...the plug & play radio harness does not use this plug therefore no ground through the harness; just the one you may have formed by plugging in the antenna, like Simon said.
