I need to use GPS for mainly city roads, many a times in dense skyscrapper jungle of downtowns, both on foot and car, Plus a little offroad explorations. Given that, what would be a better bluetooth GPS receiver for me: one with a SiRFIII chipset or MTK.
I have been reading lot of reviews recently. Almost all claim MTK having better fix in terms of number of satellites and less "multipath" problem and longer battery life per charge than SiRFIII chipset. MTK is claimed to have kept fix even in basements and dense city downtowns where SiRF could not. But they also say SiRFIII is better when walking on foot. Some of these reviews were many months old. I dont know whats current with these chipsets.
Could you please recommend whats better for my needs today and probably recommend a specific product.
Thanks for your help guys.
