Neo 35 MP3 Player The Neo 35 is an amazing product. It uses a hard drive to store your MP3's so storage is only limited by the size of your drive. I currently have a 10Gb HD in mine and with over 1000 songs it is about 60% full. The main part of the unit slides out of it's cradle and into another cradle in the front of your computer. When intalled in the computer it behaves like a normal ATA hard drive and you can RIP or download songs directly to it. You then slide it back into the car and when powered up it runs it's own small operating system with a small menu to allow you to select songs. As great as this product is, it does have some serious downfalls. I received mine about 3 months ago and, due to series of complications and a resultant lack of motivation, I have only just got around to installing it in my car. Firstly, the Neo is very picky about how you initialise the HD. This wouldn't have been so bad except the response from SSI (when I finally managed to cajole one out of them) was to check the power. What followed was about 4 weeks and many hundreds of dollars of wild goose chase whilst I tried various hard drives (6 in all) and methods of getting 12V to the Neo. It was at least 6 weeks before I managed to speak to someone who told me to re-initialise the HD under DOS. Then it worked. The reason SSI were so adamant that it was a power problem is that the Neo is very finicky about it's power. It needs at least 2A to get the HD spinning. I managed to get it running off a PC power supply, but still had problems in the car. I eventually ran a separate 12V line from the battery, through a relay triggered by the head units remote lead, and a short, direct ground to the bolt holding the CD Changer frame. You'll also notice a black cylinder on the 12V line with a fly lead going to ground. This is a noise suppressor. The Neo has two RCA connectors at the back. The Sony head unit has a single set of RCA inputs at the back but uses an ingenious bus system (through a separate cable) to allow the head unit to recognise multiple Sony devices (CD Changers, MD Changers, and TV tuners) and control them. To attach a non-Sony device you require a small box that sits in-line and has RCA connectors for your sound source. This device is the XA-107.   On the left of the device you can see the RCA leads and bus lead to the head unit. On the right are the bus and RCA leads to the CD Changer (top), and another set of RCA's for the Neo (or other device). As soon as you plug this device in another sound source is selectable on the head unit. So that you may mount this unit in the boot you can also purchase a wired remote control. SSI have since revised the design and it comes in a plastic case and uses arrow buttons instead of the little joystick. I am waiting for the new remote before mounting it permanently. MP3 is the future of sound systems, both at home, in the car, and on the hip. The Neo is an incredible bleeding edge product. I say that because it has some very rough edges and products that follow it will use much the same idea with better implementation. That said, I now have over 1000 songs in may car and the CD Changer is looking a little superfluous.
