I'm in doubt. My inlaws bought the TomTom One XL HD-Trafic a long time ago.

Yesterday I upgraded (on an SD-card) our TomTom One XL (no HD and such, just the normal one) with Navcore 9.205 (if I am correct) and it works like a charm.

Is one of these navcores also working on the HD-traffic one? Their version is one higher then ours. I am hesitand to try the one I've put on my device.
Something tells me that because theirs is also a One XL, that it would work without any problems.
They never used and will never use the HD-traffic function.

Thanks in advance.
