My Mio p350 no longer picks up satellites. I have it set up the software on SiRF on Com 2 at 4800 baud. The GPS port used in Settings - Programs is Com 2. The GPS Hardware port is set to Com 0 (is this correct?) at 4800 baud. Access is automatic. Please help. Thanks Tom

You need to go to their website and update the firmware.

Set Baud to 57600

try using the settings and get to satellite then select autosearch It is possible your BAUD and PORT are not set correctly

I Got it!
I finally got my HTC TyTN II yesterday from Dubai.
First thing I wanted to test was the GPS. It did not work with: TomTom6, Google Maps, Yahoo Go.)
I was surfing around to find something that would help me out and have noticed that many people have the same problem.
Many people (Like me) did not know howe to setup the GPS.
Many people are saying: "You have to put it your GPS settings in Com 4 and the Baud rate on 4800 and it should work.
Well mine didn't work with those settings. (Along with other people.)
I had played with the External GPS option (Don't do this cause setting something wrongm ay cost you a HARD-Reset.)
I Was lucky that mine worked again after a SOFT-Reset. So watch out!
The standard GPS settings! (If you have changed it, Soft-reset your phone and set it up as these pictures show.)

Why am I doing this?
People buy this phone to make use of it. When something does not work why buy the phone then :S
Hope that this may help a lot of people on here and other forums, communitys & websites.

Here is my story of how I did get my GPS to work:
1. Download the GPS addresses by using QuickGPS (Start -> Programs -> QuickGPS).
(This will download info of what your GPS Reciver needs to connect to the satalites.)
2. Download a free (Well half free, You can also buy this application it will give you some extra options, but we don't need those extra options.) tool named: GPS Test. (http://www.smartphone.net/software_detail.asp?id=3170 or at http://www.pocketpc-software-downloads.com/software/t-free-pocketpc-gps-test-download-uykfcoyy.html)
(This program will scan all your mobiles com ports and Baud rates, To see what your real GPS settings are.
In my case they were: COM PORT: 4 - Baud Rate: 9600 (Notice it ain't 4800. Usaly it shows your settings with a pop-up.
When It doesn't Go to "Menu -> GPS Settings", There it will show you you're GPS settings.)
3. Install TomTom 64. Download your free map.
5. Go to the GPS settings.
(Set-up: Other NMEA GPS-Reciver -> GPS-Baud Rate -> Com. (Select the Baud rate + Com port from what the GPS Test did show you.)
6. Now wait.

What navigation software you use? All navigation software need to install correct Port and Baud Rate for work - please check it in you software.

If you need help or professional GPS-consultation or unlock you PNA, update navigation maps - please ask

From inside Tomtom, have you tried "change preferences" then scroll through to "show GPS status" then "configure" select "Other Cable NMEA GPS" select "Done" for GPS baud rate of 4800. Now select "Serial Cable on SP2 and then "Done"
Hope it helps. Philpot

Under connection settings switch off the "beam" - apparently there is a conflict between the IR beam port and one of the ports used by the GPS system. Has worked for me.

Maybe you can try on com port 7 with baud rate 57600.
