Navigator Vs TomTom One

Hi,

I currently have a TomTom 1 new edition but I have been given a 6915 Ipaq from work. I am considering giving my TT1 to my wife and getting the TT Navigator maps for the Ipaq. I am a little concerned that the GPS receiver in the Ipaq isn’t Sirf III as I find the dedicated TT! To be very quick at getting a satellite lock and keeping a signal, I’m not convinced an ‘older’ GPS receiver as used in this Ipaq will be as good but I’d really like your thoughts on how you get on.

Any positives/negatives on the handheld Vs dedicated unit (but both with TomTom) would be much appreciated.

Thanks

The 6915 uses a GPS chipset made by GlobalLocate who coincidentally now supply the chipset for the latest TomTom ONE.

Although not quite as sensitive as SiRFStarIII the chipset supplied in the 6915 (the GL20k (baseband) and GL-LN22 (RF)) is a capable solution which off loads many functions to software and so can be updated easily. It also has the QuickGPS function so ephemeris data can be pre-loaded via a data call rather than direct from the satellite.

As to whether it is a better solution than the ONE, that's a difficult question and one that only you can really answer. It offers the same navigation functionality in a different package, smaller screen etc.

It won't be quite as effective and 'may' take longer to acquire a fix as well as lose fix more often but still a lot better that earlier chipsets.
