Last I checked you could get them online for $500-600. They are phasing in the new Garmin 590. To be standard on the new RT Limited shortly.
That having been said if you have a iPhone 6 plus or large Samsung you could get at least a readable screen while riding, XM radio and Weather without the Garmin 665.
