Radio Reception...info from Doc posted earlier

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.
