I also have the Holux GPSlim 240, and a Generic one with the MTK Chipset. Both were bought from
www.buygpsnow.com which is a great place for BT receivers. I would recomend the 240. I have mine mounted under my fuse panel and it still picks up a minimum of 6 satallites. Also with the BT GPS you can use it for
Google Maps or
Live Search. I also have TomTom6, but a lot of the stores or newer item are not listed and since Live Search and Google Maps pulls it info from the web it seems to be more up to date, only down side is that you have to be in the coverage area to use Live Search and Google Maps..
