I purchased a 2005 Honda Odyssey EX/L. The head unit in the vehicle has the "xm ready" logo on it, but I can't find any information about an xm direct connector, nor does honda list anything at their website except for an xm upgrade/head unit for the non ex vehicles. Can I add the terk tuner and have it integrate with the factory head unit? Is there an XM direct adapter available for the terk? Honda america, the dealer don't seem to have a clue. Any help appreciated.
