wife is looking at buying an 08 Tribeca LTD. with nav.. she also wants Sirius radio. the sales pamphlet says the nav. system comes with XM. standard. The salesman said we could get nav> with either XM or Sirius. Which is correct?
"All Tribeca models equipped with navigation have standard XM® Satellite Radio (three-month trial subscription is included, then subscriptions must be purchased separately). All models not equipped with factory-installed navigation are pre-wired for either XM or SIRIUS® Satellite Radio (hardware and subscriptions must be purchased separately)."
