So I have a Garmin eTrex Vista HCX (for hiking). It can do road navigation as well just beeps instead of talking.

The screen is however extremely small and I was wondering if their is a way I can still use my current GPS but merely display it on a larger screen for example on my a) 2013 Hilux Infotainment Centre Screen or b) 10' Lenovo Flex IdeaPad.

Any suggestions would be appreciated.
