Can I transfer albums from my store bought cd to this juke box

Okay.

I live in Michigan and bought a 2014 Cayman S this summer, it will be parked in an indoor storage facility WITHOUT electricity.

I've heard that you really don't want to remove the battery as it causes all kinds of havoc with the car (not sure if true).

At any rate I have a Porsche Battery Maintainer (https://www.suncoastparts.com/product/95504490054.html).

I was able to have a friend follow me and verify that the spoiler was going up at speed and down while decelerating back to 50mph. It was working perfectly. SO, it is not the spoiler mechanism itself and could be the manual switch itself, the wiring from that switch to the unit itself OR ???  As long as it works automatically when I'm driving it I can do without the manual operation for now. Raising it manually helps when washing and waxing the car for me. I do have a new switch but haven't installed it yet and I'm not positive that will fix the problem.

When I attach my Porsche battery tender it only operates for about 30 minutes before the power light begins flashing and the battery condition/program lights go out.  This happens regardless of which12v power port I’m connected to.  I have tried to initiate the connection with the ignition in the accessory position and well as when the engine is running, doors open/closed, with the same results. I took the vehicle to my Porsche dealer who told me everything was working correctly.  ?.

Recently the cabin lever that opens the frunk is not working.  The remote will still open the frunk AND the hatch will open with the lever or the remote. I've googled and searched the web. All that comes up are dead battery issues with a non opening frunk. Where do I start to fix this thing? Thanks in advance! 

Two questions regarding replacement of the Porsche battery.

1)  Is it acceptable to install a new non-OEM battery which meets all of the specifications?

2)  Is it critical or necessary to initialize the new battery after installation?

Thanks in advance.

Is it possible to retro-fit the front and rear parking assist systems?  I find it challenging to park without hitting something, particularly in the front, given the very low height of the car with attendent lack of visibility.

Why does the heater/air conditioner fan (2015 Cayman), which I turn off (and the display says it's off), always is back on when I restart? 

The rear hatch on my 2006 Cayman S will not open with either of my remotes. I has done so in the recent past so this is a new issue. Works fine with the lever by the driver's seat. And the remotes work fine for locking and for the frunk. Looking for suggestions before I start digging in. I'm assuming it might be a faulty actuator, but I know BMW's and nothing about the Porsche arrangement. Any suggestions welcomed. Thanks.

If I'm playing preset radio choice #4, or something other than #1, before turning off the motor,  upon returning about ten or more minutes later, choice #4 will be playing with the title and artist displayed but the highlighted choice is #1.  On some occaisons, a third station will be playing with the artist and title from the previous station while #1 is highlighted.  Essentially, the station display changes after the vehicle is shut off and then restarted.
