I have a tomtom one 130 series..im not familiar with gps sytems at all! It was working fine till i tried to update from my laptop a few days ago! I called the tomtom technical support and they told me most likely i have a currupted application? Ok soo they had me format it and it kept giving me errors? Well, after they had me format it and had everything erased they told me theirs nothin else they could do!? I have no clue what to do? Soo i joined the forum to try to get some help! Thank you for reading!
