Now that Garmin tells me that there will be no further map support I think it's time to retire my Garmin StreetPilot 2610. What is the groups wisdom on the relative merits of the Zumo 550, 660 and 665. Is it worth the extra $150 for the XM radio and other goodies? Is there an issue with sun glare with either or all? And finally, is the motorcycle mount supplied with the Zumo compatible with a RAM mount?
I have read some reviews for the 665 that complain of problems with the XM receiver becoming disabled. This requires a "hard reset" to get XM feature back in operation which also removes data such as favorite routes, etc. Has anyone had these issues with the 665? All input will be greatly appreciated.
