while driving to Florida from NY my newly installed Avic-z1 kept rebooting. i installed the system myself (18 Years as an auto electronics installer) i have double checked and isolated all connections, all OK. is this problem a programming or hardware problem? Version 1.00 software on a unit made after June of 06.

Year/make/model of the vehicle. When you say it reboots, you mean it's totally shutting down?

Year 2003

Make Chevy Conversion van

Model 1500 AWD

Yes it totally shuts down then reboots as if key was turned off then on again. i have the chime relay installed so everything works as if it where a factory radio. had a Avic N2 installed before with out any problem till the screen crapped out.

I'd look into the datbus interface being suspect. Try running an accy wire from the ignition. If it stops randomly rebooting then oyu know it's the interface causing the problem.
