ok i have new information. i spoke with the ebay
store today about my caska that will ship out today. they have confirmed this...
both caska and rosen are in fact the same unit made in china, the differences being that Rosen does not have it's own manufacturer. they buy the units from Caska and Caska was asked to redesign the GUI to make it look different.
i cant say in particular which has these features and which has other features but this explains why the Rosen costs more because they are trying to eek out a profit after purchasing them from Caska.
Rosen also charges extra for the Ipod cables and harness to connect to a XM tuner.
the Caska unit comes with everything you need.
i am expecting an owners manuel any minute via email that i plan to read so i know what the unit does before it gets here.
i was told that the map updates will be available soon because they are currently sourcing which company they will use to update the maps and what the cost will be.
i was told the units come with the 2010 map database. but i do not think the new map upgrades will cost much.
Both units use a windows CE platform
they both share all the same hardware, chips, screen cables ect...
i read on crutchfield that rosen has a TMC weather tuner and i asked if caska has this capability as well, but he didnt think it did and i am hopeing he will check into it.
as far as features, i am sure there are differences between the Rosen and Caska considering the GUI menus are different and i am sure the rosen units are capable of more features than they are shipped with but to make them identical would be stupid to compete with your own manufacturer.
so logic tells me that since caska is the parent company its more likely thoes units will have more features.
ill reply to this thread as i get more info so if your interested you might want to subscribe.
