Gps i have a tomtom go 510, when i switch it on theres a green background with a picture of a memory card with a red cross going through it. the memory is inserted! what can the problem be??? help!!!!

Try taking the memory card out and giving the contacts a quick clean with a lint free cloth

danaged card or blank

This problem is due to the memory card not containing the TomTom application or map. To update the application onto the memory card, Connect the device to your computer. Open the TomTom Home application. Click on 'Update My Device'. This should then install the application onto the SD card. Alternativly, you could perform all the steps above without the SD card in the device, this will install the application onto the internal memory. Note: you may also need to install your maps, voices, etc after you update.

my tom tom 510 would start, i have charge the tomtom with green light on, but tomtom is not coming up

I did find out how to solve the problem. I can't remember exactly where I found the solution but I think it was on TOMTOM website. You have to connect to TOMTOM home and reinstall the application. I put the TOMTOM disc in the computer (which came with purchase) and reinstalled the program. Which I thought was weird as everything appeard to be fine with TOMTOM home). Anyway, it worked. Good luck.

Try the clear flash utility. It worked for me. Martin
