Slow TT5 & TTWired fix

For the past couple of months I've noticed it taking longer than I would expect (and have previously exprienced with TT3 and 5) for my wired TT to get a fix (no change to vehicle or antenna positioning).

I've just looked in the TT5 bugs list in the sticky on this forum and seen:

"- degraded GPS performance with the new GPS driver using both third-party and TomTom GPS hardware. Probably due to the higher processor load, but it is also possible this is caused by (unnecessary) initialisation attempts upon connection to the receiver.Workaround: allow the receiver plenty of time to get a fix BEFORE running TTN. "

Is this likely to be the cause? I have 5.210 and GPS 1.20.
Did all releases of 5.xxx come with GPS 1.20? (I don't want to install and older version just to find out).

So the solution is to pull the lead from the PDA until the LED goes green?

Cheers,
Jon.

If you don't use your GPS on a daily or frequent basis, it could be the small battery in the Wired GPS unit being flat, this causes the GPS to have to download all the sat info before it can get a fix, rather than reading it from memory.

I didn't think the TT wired had a battery in it!? (But then I've never opened it up to see - surely it would be flash RAM rather than something that needed battery backup?)

In any case I get the symptoms if I've been running with all 5 bars signal strength. Stop the car for 5 minutes. Get back in and it can be 5 minutes before it gets signal again.

I'm going to experiment tonight with how long it takes to get fix if the antenna is not plugged into the PDA as the idea from the bugs list that TT5 via the PDA may be sendng too many initialisations would fit the symptoms.
