Navman iCN 520

[dazling]

I got 1 of these on its way from ebay at an ultra bargain price because the battery dont hold a charge.
My question is can i put Tom Tom on this if i dont like the navman software?

the answer is yes, not sure if the latest tt software works but ver 5 or maybe 6 works i did it but went back to navman software cos it didnt crash the tt did at least once a day.

i might have another go now cos the navman 520 maps are not upgradeable and they are a few years out of data now.
