All of the Jensen CDH1000 units default back down to 11 on the volume after a minute or so of the ignition being turned off. All the other modes such as fad, treble, bass, and balance retain their settings when set through the SEL mode (same as you set the volume level). This occurs on three units in three separate vehicles. So each time you get in the vehicle, you must raise the volume level to about 20 or so for listening. Since the clock and other settings remain correct, any idea if Jensen had this problem and could not rectify? Thanx,

If the HU was installed correctly and all memory presets and clock remain accurate, my guess is that Jensen opted for an auto-mute circuit that resets volume at a low output preset, after the HU is shut off via the IGN/ACC circuit.
This prevents someone from jumping in the car and getting blasted by high SPL from the previous driver. Not a bad idea if this is Mom or Pops car and kiddo took it out the night before and jammed to his/her hearts content. GRIN
Considering Jensen was one of the early ground breakers in car audio Aftermarket gear, it would make sense to use a feature like this for thier now aging baby boomers. In the early days, Jensen, Pioneer & Rockford Fosgate lead the vangard from plain vanilla OEM radios to what we now see today.
In short, 3 of 3 units all do this... it's designed that way and not a flaw or mistep on Jensen's part. Actually, a pretty intelligent feature, if it can be defeated by menu settings.
FYI: The manual does not mention or explain this feature.

This is so when you turn your system on, it doesn't blast you out of the car. most units used to have a 'as you left it' but this is to save you speakers.
Also, when you switched from CD to radio, there was a signal strength difference as most stations boosted their output..so when you removed a tape (or cd), the radio would blast 9 dB louder. Coincidentally, Pioneer has a signal strength adjustment you can make. I believe it's called level adjustment for this purpose.
There's nothing wrong with this, just saving you speakers.
