So I finally was able to open the Frunk - Keyfob worked better than the switch.
connected the Jumper Cables as prescribed in the manual.
No funny notifications as before now. Porsche logo comes on the display/Navi screen and radio comes on. Was able to close the windows back up.
Used the jump-start procedure as described. Nothing happens (well looks like some solenoid activates - click sound - and the screens go blank.
Maybe my VW Jetta IV battery not too strong to jump
- Will try my XC90 ones - but bummer - the battery of that machine is in the back !
Will keep a lookout for more advise...before biting the bullet and calling someone to help!
Any Plano TX owners here who can help? I don't have an OBII
