Is there any way to delete maps off of the Tom Tom USA app? It currently is over 2GB and I will not visit any states that are on the west coast. I would like to delete those maps and clear up space on my iphone. I love that it has voice navigation wit street names and you can pull addresses directly from your address book. I have tried Navigon and Wize because they are smaller file sizes but I am looking for other alternatives besides those since they did not work with my in dash stereo. It would be idea to delete Tom Tom maps or other Tom Tom features like voices and languages that I will not use. Does anyone know how to do this (or another app that is smaller that I could try)? I am jailbroken on a 4s with 5.0.1. Step by step instructions would be appreciated. Thank you.
