Help with Double DIN conversion

[KevinH1990]

Is it possible that there is a defect in the headunit? (The only way I can think to check that is to swap in a different unit.)

There are some differences between the 2000 and 2003 Boxster audio systems, and I don't think I can apply my experience directly to your conditions. I guess if I ran into the problem you have, I would check for a loose wire before I swapped the headunit. Did you solder the connections or use crimp connectors?

Soldered connections, unit removed and replaced 3 times for troubleshooting. The connectors are solid. Its losing power due to vehicle motion which makes me thing either the vehicle stops providing power, or the unit senses the motion though its GPS and shuts itself down. very safe that, there's no way it can distract you while driving.
