<DIV><SPAN><FONT face=Arial size=2>This isn't strictly OSM-related, but I do
use my Bluetooth GPS unit to take tracks with my smartphone, so I suppose it
applies. I'm just looking at this Navman unit with the SS3 chipset, it's got
good reviews and apparently it's quite sensitive - but more importantly, is
it accurate?</FONT></SPAN></DIV>

<DIV><SPAN><FONT face=Arial size=2>Does the SiRFstar III chipset have a
tendency to 'drift' when you're travelling at slow velocities (like my
SS2-based QStarz receiver does?) I think my old receiver gets confused with
bounce off high buildings too, so I'm wondering whether the SS3 chipset
improves on these problems or whether it's one to avoid.</FONT></SPAN></DIV>

<DIV><BR>This article gives a good idea of the accuracy of the SS3 chipset...

which QStarz receiver you have, but the ones on the wiki seem to be all MTK

<DIV><SPAN class=011333710-02072008><FONT face=Arial color=#0000ff size=2>Mine's
the BT-Q880 - small blue device, three LEDs, rubberised surface with a magnetic
underside (it came with a self-adhesive mounting sticker for the car but that's
long gone!). For pics and specs, just tap Qstarz BT-Q880 into Google.

<DIV><SPAN class=011333710-02072008><FONT face=Arial color=#0000ff

official QStarz site says it has an RFMD chipset inside. I got mine a few
years ago now (must be approaching three years ago now) so I doubt mine has a
SS3 chip in it. ;)</FONT></SPAN></DIV></BODY></HTML>
