New Navman iCN 650 Crashes on Start up...Please Help?

[sht]

I have just purchased this from Amazon.co.uk and it was delivered last night. I switched it on to have a play around with it setting a few destinations, it was functioning ok

Today I switched it on to try out these destinations however on startup when it was loading the maps halfway through I get an error message:-

Error
os_init: mapcasche @00ef2450,
size = 40111024[]
: routebuffer @ 03533000,

Restart

Can anyone please help with this?

Thanks in advance
