A couple quick ques. Does the D2 have RDS to recognize songs and stations like my factory radio. Also which way to go on the satellite radio. XM for the Navigation features. Or Sirius which I've always liked I have the prn1 or if I go sirius should I go the prn2 route. I do already have the prn1 setup though. thanks guys?

The D2 doesn't have RDS.

I prefer XM over Sirius on the D2, but not for the Navtraffic features.

XM is integrated much more nicely than Sirius. Sirius is clumbsy and featureless.

The only difference between the PNR1 and PNR2 was the addition of a sports tracker feature, so if thats not a big deal stick with your PNR1. I have both Sirius and XM. Sirius has better music in my opinion, XM has a better looking interface. I wouldn't even keep it except for the XM navtraffic. Like most on this board would suggest, you can listen to the free trial online and decide which you prefer
