I had TomTom GO installed on phone but after an update it refused to open. After removing I tried to redownload it but keeps saying insufficient memory. I removed all programs I installed and tried to install TomTom again, when I try to download maps I am still informed insufficient memory .. all that is on phone is what it came with. It also has a 125 GB SD CARD I am baffled as what to do next. Can anyone help
