If an installer puts too much pressure on an individual jack and breaks the ground, you can get signal loss until the unit heats up and the metal expands, creating the connection. The car bouncing around may cause intermittent loss here also.

But again, as far as the key fob goes, that's really weird. I still think there's some kind of electrical issue going on there. I haven't heard anything at all about aftermarket systems putting out any kind of signal strong enough to keep the fob from working, but there's always a first time for everything.
Jacks are solid. Not sure if the two issues are related but I suspect they are.

has anyone examined the rfid module in the car that recognizes the key...or perhaps any of the individual rfid antennas? There are 8 on the car or the remote keyless module itself. There is nothing behind the radio that relates to the key fob.

Verdict from my audio shop:

-Head unit is bad and needs exchange. Going to ask the amazon vendor to do an exchange but I'm not too hopeful. Really don't want to have to ship it to Pioneer out West but that may be my only option. Shop says that the speakers cutting out has to do with the nav system doing "something weird". They also said my wiring was good and save for a couple loose connections, everything looked to be in order.

-Key fob is Nissan's issue and they need to handle it. Dealership said the next step would be to replace the module (which I suspect may fix the issue).

This support model sucks.

"Yes gee we're sorry your head unit failed under warranty, please uninstall it and ship it across the damn country at your own expense without a RMA number and we'll try to fix it"

No advance replacement? Why do I have to pay shipping? UGH.

good reason to shop local and support your local business, they would have had that swapped out same day

dmhenderson 08-20-2012 09:33 PM
Ok well no one local had this HU. I pre-ordered it 2 months before it was released and ended up getting it for $300 less than list. I'll probably spend 2-3 weeks being annoyed at the lack of a radio (during the winter when the car is garaged anyway) but still doesn't justify paying retail.

dmhenderson 08-20-2012 09:47 PM
But if there had been a local place offering a preoder for the same price, I would have done it in a heartbeat.

So the key fob mystery is solved!

("Someone" may have forgotten to reconnect half of the wiring harness for the RFID detector module at some point during a stereo install )

*cough*

dmhenderson 08-21-2012 02:15 PM
So add to the knowledge base for the RFID system that if you disconnect half of the plugs, it ends up exhibiting some REALLY odd behavior sometimes.

sucks, but I'm not surprised. Glad you got it figured out.

dmhenderson 08-21-2012 05:04 PM
Wait we're not done yet. I go to pick up the car and now the entire antenna system is totally dead. Dead as in, "can't unlock the doors from outside the car, key fobs not detected anywhere inside or outside the vehicle, car will not start unless fob is inserted in fobgina"

Is there a way to reset the antenna module? I feel like bashing my head into a wall.

dmhenderson 08-21-2012 05:05 PM
ROund 19231983281923 with the dealership tomorrow if I can't figure it out. At this point I don't even care if they charge me I just want it fixed.

Not gonna take it apart again. I checked the installer's work and it looks good to me. Done it 3x and can't find the fault and dammit, I'm pretty good at this stuff. Taking it to my audio specialist tomorrow morning.
I'm just gonna leave this here. For the historical records. Hope you get it sorted out, sounds like a bigger mess than when you started.

"Fobgina" that is "F"ing hysterical! I feel for you after reading everything, but the fobgina nearly put me on the floor. I'm now looking into a new headunit and this will be useful info.
