Supported SD Cards

[sap283]

I am planning to purchase A-DATA Turbo 8GB Secure Digital High-Capacity (SDHC) Flash Card Model TurboSD SDHC 8G (This is 8GB SDHC Class 6) card.

Does TomTom Go 720, support 8 GB SD card? Also, does anyone know what maximum data transfer speed it supports i.e. Class 2, 4 or 6?

Thanks,

With firmware 8.3, a 720 can deal with a sdhc card of over 4 gigs, and a class 6 works....

with firmware less than 8.3, a 720 can read/write to a 4 gig card but only read from a card > 4 gigs. you'd need a card reader to install stuff in the upper limit of that sized card.

Little confused.

so, If I have latest firmware, then 8GB- SDHC class 6 should be OK , you mean?

Thanks,

Should not be a problem but get a known sdhc card from a known company (such as SanDisk).

OTOH, the two SDHC cards I bought new, a TopRam 4GB class 6 and PNY 8GB class 4 worked right from the package and never caused any problem since. I almost always use my TT with one of those two cards.

The SDHC cards were meant to work ONLY with the Go series of TT units. While some have gotten sdhc cards to work with non-Go units, it isn't a sure thing.
