Aftermarket stereo boot delay
Installed an aftermarket stereo which works well aside from a boot delay. It can take 30 seconds to several minutes to start after the car starts. I added a ground on the metal mount below the climate control. Has low resistance but curious if that could cause an issue like this. Had same problem on two units now. Are there other grounds I should check or test the wire harness in some way? Stock radio didn't have this problem.

Yes it's the Axxess one. Just talked to crutchfield and they said there's a software update for a power drain issue on those units. So I'll check that out. I installed a kill switch because the battery kept draining when I had the aftermarket unit hooked up. Anyway, if that doesn't fix it, nothing else to do short of replacing the Bose system?

Use diodes and hook up the power on wire into an accessory wire. That way it can receive power from the Axxess unit or accessory power, and diodes prevent backfeeding into either system.

Thanks. I just updated the Axxess interface with their pc program. It was version 2.4, updated to 3.5. It did not fix the delayed boot issue, but I'm leaving the kill switch off tonight to see if it fixed the battery voltage drain issue. It would be nice to at least not have to use the kill switch all the time.

What size diodes would you recommend for this?
And which Accessory source would you tap?
Thanks,
Jim

The radio power on wire doesn't carry that much current, any diode that can handle at least 2 amps will be enough. Most radio power comes from the yellow wire. I would recommend a 5 amp diode, as those seem to be readily available and gives safety room.
