Chartplotter distinction

[Deadline]

1. Any material distinction between the Garman GPS Map 541 and 640?
2. Do they both show XM radio radar?
3. Will XM radar preclude the whole dome set-up? Thanks.

I think there may be some confusion regarding the whole XM radio and Radar issue. Were talking about two completely different things. To use the chartplotter display in conjunction with a Radar scanner, the unit must be compatible with Garmin's network system. Neither the 541 or 640 appear to have that capability.
