For those of you with the Navi unit, and have considered spending $320 on the Honda iPod adapter, save your money. Don't get me wrong, I love my iPod, but Honda's connectivity for it leaves a lot to be desired. The built-in mysterious PC Card interface is actually better. Just tested a SanDisk Extreme III 8GB compact flash card with a SanDisk Ultra PC Card Adapter and I'm happy to report that it works perfectly.
I loaded the card up to the max with 8GB of MP3s, stuck it in the Navi unit and it started up in about 5 seconds. The ultimate limitation is the 999 song limit. It reads the first 999 tracks it finds, indexing through the folders alphabetically. I had 1440 tracks on the card, but only the first 999 were recognized by the unit.
I tried this previously with two different 2GB SD cards. It behaved very poorly. The Navi unit would skip over about half of the MP3s. At first I thought that the MP3 encoding for some of my tracks were not compatible. I later found that those same songs played fine if I reduced the number of tracks stored in the 2GB card to only 1GB. This is way I switched to compact flash.
Here's some pics for those of you with Navi systems that haven't seen the PC Card interface. There's a lot "under the hood" of this little known feature.
