TT One V3 and 870 maps

The Western_Europe_1GB_870_3417 maps are approximately 100MB larger than for example 850. They will not fit on One V3. Anyone got a suggestion how to get the 870 maps onto One V3?

Choose a smaller map or a a part of the map.
The Europe Central should fit.
Please check the size of the map in the thread first, the sizes are listed too.
But more and more 875 maps are coming, so you might want to check there to get an up to date map.

Thanks, will try a smaller map.
