Is there any differenc in a A SD card that is HC or not ? Would assume the FSerious is slow already that there is no performance difference in faster cards.

It will take it. Regardless of the speed of Avic why not get HC anyway?

It will be faster when you are putting files on it on your PC. But if you are putting small files on then it would not matter.

Thanks fro re in SD issue i just had some cards that were not HC and was wondering if it was worth going out and spending money on HC card thats all.

I think its only some older cameras that are not compatible with High compression but I use my 4 gig card in my 900bt all the time with no troubles

I have a 4GB HC as well and the only reason I went with it is because Best Buy had them for super cheap. They were like $12 for SanDisk. A week later they were $30.

I would not spend money on HC unless you are transferring a lot of stuff back and forth.

What is the maximum capacity on an SD card that I could use on the F700BT?

8 gigs.

I saw a 4 gig hdhc for 5 bucks...

Keep checking bensbargains.net

The manual says 8GB I think but I'm using a 16GB SDHC card without any problem. A little slow to load with 13GB of music but that was expected. I've seen other postings where people are using a 32GB card.

It seems with USB and SD it's kind of pot luck. I was using a 40GB 2.5" USB hard drive on my previous Pioneer HU but it doesn't work on the F700, even with external power. Go figure. Time for an Ipod.

Can some other people post the size cards that they have used already?

Cards i've used.

Sandisk SDHC Ultra II 8GB

Sandisk SDHC Ultra II 4GB

Sandisk SDHC Extreme III 4GB

A-Data Class 6 - 8 Gig

Kingston Class 4 - 8 Gig

Kingston Class 4 - 16 Gig

No difference in the Class4 and Class6 for access time, F90bt is still slow as fsck reading an SD card, especially with videos
