I recently got some good deals on SD cards at a boxing day sale.
I bought a couple 2GB and a couple 4GB cards because I wasn't sure which would be better in my nuvi 650. I'm looking to keep one kind and return the other.
I understand there are some limitations regarding the # of mp3 files that can be stored on an SD card or read by the GPS unit.
I also understand a larger capacity card my slow down loading times of the unit itself - not sure how much slower or if it makes much of a difference.
Which card would be better all round? 2GB or 4GB.
Which card do you use?
How fast are you cards?

Do you have any idea how fast your cards are rated? this will help....
4gb
I use the 4gb card in my 660. I don't load my POI's on it, so I don't notice any slow downs. Heck I took out every vehicle in it except the one I use and the arrow (Saved it on my laptop) and now have 475mb of room free. I have 350,000+ custom POI's already loaded. So with 475mb free, and 350k only takes 38kb in size. I guess I could load a few million more.

not sure how they are
not sure how they are rated.
2GB is an SD card - 4GB is an SDHC card
Nope.

2GB is an SD card - 4GB is an SDHC card
My 4gb SD card is NOT a SDHC card. I know this because I used them in my PDA (Axim x51v) which is not capable of reading SDHC cards.

So, is it better to load
So, is it better to load POIs onto the unit memory and not the card? Is loading the POIs on the card what slows the unit down?
Not sure yet how the GPS works. Does it read the card every time it redraws a map - or only when it accesses an mp3 or POI file?
using memory card
it makes sense to use internal memory only for everyday routine - enough space for your typical POI and use mem.card for downloading temp POI regarding your trip location.
SD card vs Internal memory
This is an interesting topic...
It's important to select a GPS that has at least 2GB of internal memory. Helps keep those added POI's/maps readily avaialble. The added expansion port can be used for additional maps, mp3's, photo's etc.... while you can store POI's on an SD card it is preferable to install in internal memory. I've personaly noticed a slight delay when retrieving large POI files with The GARMIN and LG unit.
Hope this helps.

4gb slower
I did some experimenting awhile back...documented here: http://www.poi-factory.com/node/6706
