well i'm new to the Z world but not the nissan world. recently purchased a fantastic fully functional 2005 35th anniversary edition Z.



i love everything about the car, but i have made the fatal mistake of taking it to a dealership to have the oil changed rather than doing it myself because i figured they would treat a Z with respect. got home and decided to program the navigation with my home address, etc. etc. and when i pushed the button to open it the door magically stopped working. it would only go half way up, stop, and close again. i called the dealership and of course they said they never touched it but for the low low price of 700 dollars they could replace it all.

so after looking through the threads here i took apart the dash and found a tooth broken off of the door and jammed. sighed a breath of relief, put everything back together. and now only when turning the key, the door will open fully, stop, and close. the navigation never turns on. so i took it apart again and ran it with the circuit board in my hand and tried to run the limit switch by hand...nothing. i ohm'd out the switch and it seems to be working. Any ideas for this?? i'm thinking the circuit board behind the instrument cluster is bad but i wanna make sure before i spend $200+ to not fix it.

its not the navigation fuse. while Nav door is unplugged the Nav will turn on.

sorry this is so long, thanks for any help.

 

^^ You describe a common problem on the 2004 and 2005 350z with OEM GPS. The GPS function is tied to the motorized door, and when one fails (typically it’s the door), you lose your GPS function.

Since the GPS system in the 2004/5 350z is a dinosaur, your repair plan should be a replacement plan.

 

but I don't know what to replace, the limit switch on the circuit board attached to the door shows the switch is acting right. But I'm not sure of other functions on that board. So do I replace that one or the board behind the instrument cluster?

 

You'll soon realize the factory navigation is worthless. It's significantly slower, harder to update, harder to program, has more restrictions and is far bigger pain than your phone...mark my words, OEMs will stop putting navigation in cars...because everyone has a smartphone and a tablet connected to the internet.

 

Basically this. I looked into getting an OEM nav set for my car but realized how ancient the tech for it is, they want you to update using factory update discs or some nonsense. Far cheaper to find a modern lifetime map update gps or android tablet that fits and make a bezel/mount.

 

Spike isn't saying replace parts on the OEM system rather scrap the entire system and buy a double din with nav or w/o and use your phone for nav

 

You are correct and thanks for help clarifying my first message. The OP needs to scrap (remove) the OEM Clarion navigation and replace this with an aftermarket unit. Or, I guess he could simply use his smartphone as others suggest here.
