GPS chip any good?

[mlehtola]

HI,

my Qtek 9100 went broken...it has TomTom 6 and TT's bluetooth GPS receiver (SiRF). Is Polaris's chip (Qualcomm 7200) anything like SiRF or is it "useless", is it a-gps?

I find that the built in gps does the job well. I doesn't have to be on the windshield or dashboard and still it has enough signal to drive you from A to B.

My globalsat BT-359 is an external bluetooth receiver and gives a fix much faster than the MSM7200 in difficult condition likes when you are surrounded by buildings, etc... I have no doubt that sirf III is more sensitiv and tracks signals better. But the MSM7200 is more than enough for me and my normal usage.

I don't have athermic so I can't comment on that.

Mine works perfect in London, it is my first GPS and as a novice it just worked straight off my lap in the car.

It's OK. LAT/LON is very good, but it doesn't lock as many sats as a SiRFStar III so not quite so hot in low coverage areas.

The other odd thing I've noticed about this chip is that the altitude reported is wrong, by about 150ft. Not needed for driving though.

So, not the best, but good enough most of the time.

I agree with LargePig....

LargePig put it very well. Sirf III is the best on the market, but the Qualcomm chip does a very respectable job grabing satelites and positioning data for navigation.

I can't say I've tested it in one of the great urban canyons of nyc, but in the residential areas I have no problems with the navigation system.
