i have some similar sort of problem on my TP1 where the gps kind of momentarily completely lose track of all GPS for about half a sec every so often (even though all the sat signals were all the way up). This was really independent of how fast I was moving. Additionally it has some horrible lag problem when my speed gets to about 50mph during which the whole thing just sorta freeze and won't update or scroll the map at all for several seconds...

My TP2 definitely does not have the above problems. solid steady lock, no problem with keeping an update on the position (very slight lag but never problem with updating position or scrolling the map)... Is this some new problem you just experience recently or has this been present since the first time you use the gps? I would definitely exchange it if i can.
