I used a GPS speedo app prior to the update without any problems. Since the update, Google Maps actually locks in real quick and accurate, however, trying to run these speedometer apps just dont ever work. I do activate the standalone GPS box, but nothing. Has anyone else experienced this or have any suggestions?
Have you tried clear cache and data in the application setting menu? If not menu>settings>applications>manage applications>downloaded>find GPS speedo and clear the cache and data then try using the app. Hope this helps
