You gotta love open source!
I have a Neo35 car MP3 disk system - thirty gigs of MP3s in the boot and a wired remote on the dash - very nice - all my CDs in the car! Anyhow - about a year ago (and a few days outside the warranty period!) it developed an annoying fault whereby the back key would randomly press itself (sending the song back to the start). Once this started it was like it until you reset and sometimes you had a few minutes grace, sometimes half an hour. I was is a logic issue as it does it whether the wired remote is attached or even if the disk is in the USB caddy you use to download into it on the PC. Ho hum - then, along comes the Open Neo Project where the company has opened the firmware to the wider programming community and they've produced a version that allows you to re-map the keys - nuff said! I'm back in-car-MP3-nirvana!
