I purchased a Yaris ZR (2012) which comes with Toyota's new TECH system. I have had nothing but problems with it where the GPS loses signal whilst driving and can remain lost for up to 15 minutes until restored. I have taken my car twice to Toyota for the problem to be fixed, however I have been notified now that this problem is on all multiple Toyota models with the TECH system (not just the Yaris). There is no current fix for this, and the problem renders the navigation system unreliable and many times useless. I searched the net however I have seen no mentioned of this issue. Has anyone else experienced this issue with new models using the TECH system?
