Ok, so I updated my Thunderbolt last week to: Android Version 2.3.7 Baseban Version: 1.48.00.0906w_1.0.01.78.096w_2 Kernal Version: 188.8.131.52-cm-shed-2+ MOD Version: ThunderShed-v15_CM7.2_Tbolt Before that my Navigation used to lock every time at high speeds. Now it does not lock at all. Maps detect my location, but GPS just states "Searching fro GPS" and nothing else happens. I have searched online for any solution, to no success. I have changed my radio drivers, gps.conf file, used the gps status software, tried different roms, but nothing seems to be working. Can anyone here help me out, its driving me crazy. If you have a rom which works great with gps, speed, and 4g lte, please let me know where I can find it and install. I use it quite often and now I have to go the old fashion way, using Google to print out directions. Thanks in advanced. P.S. - I have also gone to the previous rom I had, and still not working.
