In regards to sled / PCB necessitation...

I was planning on a having a plastic box type thing fit tightly around the unit with the unit slides in to. It would be just slightly longer than the Empeg. It would have an integrated FM transmitter that is controllable via the Empeg (perhaps a patch to make it work in Hijack) so you can change the FM channel, etc... There would also be a plug for a cigarette lighter, and a headphone jack. The "box" would come with some sort of firction creating devices to mount it (i.e. suction cups and a bracket, or some velcro or something) so you can set it on the dash without it sliding away.

Any suggestions on this more detailed idea?
