Once I get my Pure (ordered without radio), my plan is to add the Eclipse ANV2210p with TomTom GPS Navigator and then add to it the Sirius radio option. I have Sirius on both my other cars and prefer it to XM (less self-promotion ads for other channels). Also, Sirius lets you buy a $500 lifetime membership (lifetime of radio) which I prefer to monthly/yearly subscriptions (fire and forget).
