Hi, 

When i look what maps that are installed on my 830 there are like 4 EU maps, one from 2017, The only featuer i want is trailforks and of course a map off my homecontry Sweden

My first bike computer and Tough i get some awesome Info about my rides

I have issues with trailforks, cant remember The exact words. But i want to open up maps, it always returns unable to open up maps.. GPS is a mess,

Can someone contact me and give me a step by step guide how to remove maps wich i dont use and other data and help me with trailforks 

Thank you
