Memory Map slow to load

[wafupilot]

Memory map takes up to a minute to open on my orbit 2. On my wife's phone, an Orbit 2 also, it takes just 5-6 secs. I am running Tomtom, she has co-pilot........... could this be the problem ?

On paper I have a faster micro sd card..... obviously :p:p

Any suggestions would be gratefully received.
