The other day, I was testing on a sprint/slalom course in my Lotus Elise with the Empeg mounted in the dash (powered off of course). After a few runs, on the next start the car flew off the line but the Empeg didn't. It flew from its sled into the cabin instead!

Luckily I had a passenger on board so it just embedded itself into his legs, which are considerably softer than the bare aluminium floor. No damage to the Empeg. Only a minor scream of pain from the passenger (apparently, he was thankful it hadn't landed a few inches further back or it would have been in a very sensitive place).

However, I'd like to be able to stop it happening again. I mean, I don't always have a nice soft passenger for it to land on. Also, this was in the wet - in the dry the car will be making even faster starts and I presume that'll make the Empeg fall out of the sled more easily. Is there anything I can do to make it stay put a bit better, but still be removable every now and then to add new music etc?
