I purchased this device and updated the maps to 835.2423. I am now looking to update to USA & Canada v850.2783 [836MB]. As that appears to be the only option due to the 1 gig limitation. Am I correct in stating that IQ and ALG is not an option for US maps as they are over 1 gig? Also this devices time to destination calculations are way off and route planning has not been very good either. This could be due to the fact that known speed limits are not being displayed so therefore it can not calculate correctly. Do you think updating the Navcore along with the maps will help at all? If so which navcore do you recommend? Any links on the sequence I should follow to update maps/navcore will be appreciated. Thanks for your time.
