SD and SDHC cards on Garmin Nuvi 770

Please can anyone advice if they know whether SDHC cards will work in the Garmin Nuvi 770 and also if a 4 gb or 8 gb SD card will work too.

I'd rather have a high capacity CD or SDHC card in my Garmin, so I can store, pictures, music/MP3 as well as downloaded maps apart from the standard Maps that are pre loaded on my unit

Thank you for your anticipated response

Regards
