Navionics Cards - perennial question

[ozbee]

navonics cards are widely used in the aircraft industry they are a very big company.my son who is a computer engineer says you wont succeed ,plotter will read more than one version of sd card. note we are talking about the actual program of the chip not the data stored on the chip.the downside is when you want a upgrade and you send in your chip the company throws yours in the bin and issues you a new one even it cant access it to up date it.

Navionics need to step up to the plate and offer a solution - even if it is a small additional cost to get a 1Gb version...

[edit] DRM features

The digital rights management scheme embedded in the SD cards is defined as the Content Protection for Recordable Media (CPRM) by the 4C Entity and is centered around use of the Cryptomeria cipher (also known as C2). The specification is kept secret and is only accessible to licensees. DVD-Audio uses a very similar scheme known as Content Protection for Prerecorded Media (CPPM). This type of DRM is associated with the reclusive SDMI, an organisation set up by the RIAA to promote such hardware-based copy protection schemes. Many SD cards are marked on the packaging as being 'SDMI Compliant' for this reason. This DRM has not been seen "in the wild" and few, if any, devices appear to provide support for it.
Super*Talent, a manufacturer of computer memory, has created the "Super Digital" card. They are the same in appearance and function to regular Secure Digital cards, but they lack the CPRM code commonly found in Secure Digital cards. [9]
