I've been thinking of adding some kind of mp3 playback solution for my car, but I haven't been able to find any easy solution.<br><br>A while ago I was looking at the PhatNoise product, but I recall reading something about it not being compatible with Nav systems. Now the PhatNoise is sold by Kenwood and it appears that it only works with Kenwood decks. It's also quite expensive at $900 for a system with a 10GB cartrige.<br><br>I also looked at that cassette mp3 adapter that uses MMC card (someone mentioned it here few days ago). Unfortunately, the storage capabilties are rather limited, and the largest MMC cards are only 128MB. I haven't tried it, but I think the navigating the songs would be difficult (since the adapter doesn't have any kind of a display).<br><br>My latest idea is to somehow use the new Creative Labs Nomad Jukebox 3. If you haven't seen it, it's slightly smaller than a portable CD player and comes with 20GB of storage. It retails for $399, but you can probably get it for less if you look around. This part is good, but the problem is how do I integrate it with my system? The player has line outputs, but from what I understand the HK system does not have any line inputs? Right? Is there any kind of solution for adding line inputs (without actually replacing the tuner/amp)? Some kind of inexpensive harness that adds line inputs?<br>The other option that I'm thinking is to use a cassette adapter that Creative sells for $20. Since I have the new nav system, it should work with my system, I'd just have to figure out how to keep the nav screen closed with the adapter installed. Creative should be also making a car power adapter that plugs into the cigarette lighter, so that would solve the power problem (there is also a remote control coming). However, I'm somewhat worried about the sound quality when using the cassette adapter? Does anybody know how those things work? Is the sound quality comparable to the quality that I would get from the line outputs?<br><br>Sorry about the long post, but do you guys have any comments about my idea? Does anyone have something similar in their car? It looks like for about $400 to $450 (player with adapters) you can have a mp3 solution with 20GB of music. Plus you could always take it out, and use it for other stuff.
