GT display shows INACCURATE most of the time and acceleration measurements often fail. Why is this?

GT monitors signal accuracy constantly, and INACCURATE is shown if acceleration measurements are not possible because the results would not be precise enough. Try to relocate the GPS receiver so that it has a better view of the sky. Note that sometimes it takes up to fifteen minutes for the GPS receiver to connect to all available satellites.

I have a Nokia N95 with internal GPS receiver, but I want to use an external GPS device. How to change the GPS device?

The GPS device selection is in the phone settings. In N95 select Tools / Settings / General / Positioning / Positioning methods and then select "Bluetooth GPS" and deselect "Integrated GPS".

I registered but I don’t get acceleration results. Also Results is not visible under Options.

To get acceleration results, the top speed should be above the set speed limit (e.g. over 100 km/h for a 0-100 km/h measurement). As car's speedometers often show too large values (e.g. 100 km/h when actual speed is 94 km/h), you should make sure that you don't decelerate too early. The Results menu item is visible only if there are stored acceleration results.

You can load GT, GTi or GTx directly to your phone with your phone’s web browser. Type the web address www.tempes.com/cgi-bin/counter_gt.cgi to load GT, www.tempes.com/cgi-bin/counter_gti.cgi to load GTi or www.tempes.com/cgi-bin/counter_gtx.cgi to load GTx.

If I upgrade my phone (which I do almost yearly) will I be able to request a new registration code for the new phone at no cost?

We will provide new registration codes at no cost (within reason, e.g. once a year) for our customers.

Now you can pay also via bank transfer. When you are transferred to PayPal's page in the registration process, click Cancel and you get the necessary information.

When I start GT V1.0, it says "Connected" in the status line but nothing happens. Navicore works fine with the GPS receiver. What should I do?

Please upgrade to GT V2.0 (see the next question below). Navicore changes the settings of some GPS receivers which causes GT to fail. The new version of GT changes the GPS receiver settings back so that GT and Navicore can co-exist. Another option is to remove the GPS receiver battery for a while (if this is possible), which should reset the GPS receiver to factory settings.

How much does it cost to upgrade to a new version? Do I lose my result files and navigation destinations when I upgrade? Is there a need for registration?

Upgrading is free. GT and GTi: Do not remove the old version, just install the new version which replaces the old one. This way the old result files and navigation destinations remain intact and registration is not needed. If you have removed the old version, you should enter the same registration code as in the previous version. If you have lost your registration code please contact support@tempes.com. GTx: Uninstall the old version of GTx before upgrade (navigation destinations are lost) and send the IMEI code to support@tempes.com to get a new free registration code.

Why do I get a warning when I install GT: "Security warning. Unable to verify supplier. Continue anyway?" Does the installation file contain a virus?

S60 applications can be digitally signed for authentication. GTx is digitally signed, but GT and GTi are not. You can continue installation if you have downloaded the installation file from our download page.

Send the result file to PC (Options/Results/Open/Send) via e.g. email or Bluetooth. Your PC should open the file with Notepad when you double-click it. Copy and paste the data you want to analyse (e.g. lines between 0-10 km/h and 0-100 km/h) to Excel. In Excel click Data/Text to Columns and select Delimited, then select Space and Other as delimiters and type - (dash) as Other. You should now have speed and time values in different columns and can graph the data with e.g. XY chart. You can insert a row with zeroes for speed and time to start the graph at zero.
