Have a real mystery here. Car has ~2500 miles on it and an aftermarket head unit, amp and sub. Door speakers and tweeters were swapped out.

As space is at a premium behind the dash, the XM tuner was actually installed in the wheel well with cable run through the center console to the radio.

The car is a 2012 nismo 370z

I have two very odd issues:


ISSUE #1
Key fob detection has been slowly degrading.

-At first, the car would not see the fob(s) unless they were in my right hip pocket or in the console or passenger seat.

-Then, the car would not detect the fob unless it was actually resting in the cup holder in the center console. Earlier this week, the car wouldn't detect the fob from outside the vehicle and I had to use the physical key to enter the car but once I got inside, everything was ok.

- Most recently, I came back from lunch and the car would not respond to the fob so once again, I had to manually open the door only this time, the car would not detect the fob anywhere inside the vehicle unless the fob was inserted into the fobgina (thank god).

I took the car to Nissan yesterday and they tested the batteries in my key fobs (both good) and actually programmed a new one and swapped it out so the fobs aren't the issue.

I have another service appointment on Monday but the dealership seems mystified. Any ideas before I give it back to Nissan to play with?


ISSUE #2
-Getting weird intermittent static out of my left speakers which will occasionally cut out entirely (both tweeter and door speaker). Static seems to happen when the car is cold (???). My GPS antenna runs up the lefthand side of the windshield (underneath the joint) up to where my mic is mounted. Can the GPS antenna signal interfere with speaker wires? I've checked all the connections and everything is shrinktubed properly. No weird grounds and nothing is shorting so what the hell?
