Try a few CDA's, like that you found for R3EA037. If you don't need the languages, I wouldn't suggest a customized CDA. If you do want a customized, I'd suggest using one that's for to your locale.

Does Rogers provide GPS Navigation, like AT&T Navigator (by TeleNav)? That's the most useful program comes with AT&T, too bad it doesn't work after debranding. Wayfinder is cheaper at half the price but not nearly as good. But I'd prefer not carrying another GPS unit.
