Looks like Sirius is strengthening its relationship with Ford. Starting with the 2008 model year, Sirius Satellite Radio will be factory-installed satellite radio on the Lincoln MKZ, Lincoln MKX, Lincoln Navigator, Lincoln Navigator L and Lincoln Mark LT.

Last week Sirius announced that their satellite radios will be standard equipment in select Land Rover vehicles. Land Rover is owned by Ford Motor Co.

About 600,000 Ford, Lincoln and Mercury vehicles have already been shipped with factory-installed Sirius satellite radios. Those numbers are expected to more than double in 2007 as Sirius will be offered in 23 different models this year.

On top of being standard-equipment, a six-month pre-paid subscription to Sirius is included with each Lincoln vehicle.
