Sat Nav ( again )

[extra330]

Anyone noticed the sat nav not working in hot weather, or in winter when the heater is on ?
works from cold but when cabin warms up screen goes blank.
Not a great issue as its pretty poor, just curious

No issues with mine.... is the front plate pressed fully home?

Don't really understand why people say it's not very good, granted it's not perfect but as a tool to help with guidence I don't see an issue really.

yes front plate secure, had the front off to fix hazzard button, but always had same fault.
no worries
