First of all sorry for posting in english on a german forum, but I don't speak german at all. If this violates the TOS I appologize.
My problem is that the manual for Lucca 5.3 states clearly that the GPS is able to use SD/MMC cards up to 4Gb. I've tried at least 7 of these cards, by various producers, and none was recognized by the Lucca.
Is there any way to make 4Gb cards work with this device?
Thank you.
P.S. Almost any 2Gb card works just fine.
Hi Optimvs,
the reason is the TravelPilot 5.3 doesn't support any 4 GB HC SD card. 
You'll have to find 'old' 4 GB SD cards or use 2 GB cards.
Bye

I see, thank you for the answer. Are there any known 4Gb models that work for sure with Lucca 5.3?
I was under the impression that any SD card above 2Gb is HC.
Update: I finally found one that works, the Silicon Power SD 4Gb 80X memory card. It's a plain SD, like Jimmy said.
The code on it is 09010001-4GB-D
Silicon Power model SP004GBSDC080V10
