You can email David all you want, but we have clearly stated the warranty requirement - an original sales receipt or invoice must be presented, either from SONICblue or from one of our appointed resellers (which includes Car Toys and carplayer.com). Without that, we have no way of knowing whether a unit is within warranty or not.

The only exceptions are:

1. If you bought the unit direct from Cambridge (empeg store) in which case David already has your invoice details

2. In the case of certain known issues (e.g. hard drive cable) we probably won't ask for any proof of purchase.
