Well I was just reading throught the doc that was posted earlier today and noted the following:
Audio System
• Mid- and premium-grade head units are new.
• Audio system shares the same display with the Navigation System and HVAC.
• Mid-grade AM/FM/CD-6 in-dash with 8 speakers.
• Premium-grade Bose AM/FM/CD-6 in dash with 10 speakers and subwoofer.
• The vehicle is pre-wired for satellite radio.
• Armada uses a Diversity antenna for enhanced reception performance.
– One on the drivers side rear window
– One on the passenger side rear window
• All Titan models come with a mast-type antenna.
– These antennas have been specifically-designed for optimum reception on this particular vehicle, and use an antenna signal booster located at the upper C-pillar.
• A front auxiliary input jack for headphones and remote CD is located below the climate
controls.
This may be the cause for the 'weak reception' problems on the upgraded system. Not sure if it has anything to do with the RF system problem.
I saw that as well and was wondering why the booster is in the "C" pillar and also why the two vehicles have different systems. It would be nice to hear from some Armada owners and find out if they are having the same problems.
I received a call from my contact at Nissan yesterday regarding the reception problem in the RF radios.
He told me to take it in to the dealer and have the service tech call into Nissan directly and find out how to fix the problem.
They do have a fix! It requires the dealer to service the radio but he didn't know exactly what needed to be done, and it is completely covered under all warranties.
I plan to do this once I get back from my road trip to Florida at the end of the month. Going to have to do an oil change and tire rotation at that point so might as well get it all done at the same time.
