I have completed all instruction in this good thread to unlock my navman 50s and install tomtom. Everthing installed and worked ok except that I cannot get the GPS to work . It just says Poor gps reception are you in a building all the time.I set it to these GPS settings use
Other NMEA Receiver
Baud: 4800
GPS-COM as SirNavDrv or Com:2 were not on my options
The other other choice I had was TMC-Com which just came up as no gps detected.
I have also tried deleteing autorun.mscr. which did not help.
The gps still works ok on the orginal naveman software.
Any suggestion or advice would be much appricated
Stuart.

The error message means it's found the GPS hardware, take it outside and give it a good 20-30 minutes to download the satellite data, sometimes it just takes time for the first lock.

Thanks for the info. I'll try it with my Mio Moov M400.

I have a M400, it works a treat!

It been sitting in the garden for about 12 hours pluged into its charger so that it does not go flat and still getting same error message poor gps signal. Also spend hours on my car windscreen with same error message. Any more ideas before I return to useing an old faithful navigo.
Ps if I need to put it back to how it was before I install the hack. Is it just a case of replaceing the program folder with my back up of orginal folder
Stuart.

Try using baud rate 57600

57600 works great. signal received within 2 minutes on bedroom window. tomtom icon also working ok on front screen. Running 7.9 with map 890.4234 at present. Will just have to pick a newer map.
Thanks for your help once again.
Stuart

In some regions these device's use a different baud rate, it doesn't crop up that often, most likely a different GPS receiver is installed.

Thank you so very much for this wonderful thread and contents. I bought a second hand Navman yesterday and was unaware how out of date the map was until i started driving! (I'm relatively new to the world of SatNavs!) followed this guide and after a few hiccups I got there and have successfully installed TomTom on my NavMan s70 3D. Thank you again...... If only there was a thread like this for all of life's problems!
Thanks again and well done on a great site

You're most welcome

Hi, The links provided for the tomtom software don't seem to work for me. I just get prompts to install download software and other junk (iLivid etc..) :(

Which link are we talking about? btw don't click on the obvious download button which is an advert for ilivid disguised as a button

It's the link for the actual TomTom files, I get the prompt for the password which I enter and then I'm presented with 2 download buttons, both of which try to install ilivid. Thank you for your swift reply. :-)

I will check later, I am at work now and the internet is restricted

I still think you are pressing the obvious buttons which are the wrong ones, scroll down the page a bit further. Have sent you a PM to download mine from dropbox.
