One other thought,... I tend to use WAZE on most travels in the US. I guess I'd be subject to raining if used on SXM? Or should I use the gps map app that comes on the iPhone?


raining or roaming? <img src="http://www.traveltalkonline.com/forums/images/graemlins/Wink.gif" alt="" />...to avoid data roaming charges you would need a GPS/navigation app that stores maps on the phone, and doesn't rely on a constant data connection

with Waze and Google Maps, while on WiFi, you can download the maps to your phone for the area you'll need, then use the app for offline navigation... How to use Waze and Google Maps Offline

or you try a standalone navigation app like Be-On-Road , it's free
