I have the non-GPS factory head unit and have been looking for options to add GPS and/or Android Auto. I found a black box unit that goes behind the factory unit, but the manufacturer doesn't recommend using it with the base head unit because the screen resolution is too low. I am trying to find the best option with quality mapping. I use Android auto in my other vehicle, and it is OK unless there isn't good cell coverage. ...

missing nut. Had the car at the dealer this week fir the annual service. They found that there is a missing nut on the diagonal brace. I ask about replacing it and was told they are not a nut and bolt store. Can sone one tell me the size of the nut? Maybe even where I can buy one? Thinking about changing dealers or maybe using an independent. Thanks for the help, Dave Anderson

READ ANSWERMy 2009 997.2 (PCM3.0) does not have the AUX input in the arm rest. I have recently added a car play board to the head unit. In order to hear the sound from car play I need to choose the AUX input. To do that I have to code the car to tell it I have the AUX option (which, of course, I do not). I have a Durametric pro version. Can I do this, and if so, how? I was hoping to see AUX in the durametrics software and I'd simply switch it to Installed. No such luck!

READ ANSWERWill Battery Group H6/48 Really Work?
Thursday 04/23/2026 | 1989 | 944 S2 | Electrical
George, I saw a thread where you say to use a Group H6/48 battery in a 944. When I tried to use that size in my 968, it hit the support structure of the hood, and I had to use a Group 91 instead. Are you sure that ALL years and variations of 944 will accommodate H6/48--particularly when the windshield-washer hose can end up between the battery and the hood? To protect against any acid-leakage damage, I have recently started to use one of those thin "battery mats" below my car batteries. T ...

Watching Nathan Mertz on YouTube 1974 -1977 Porsche 2.7. He notes the 1976 as the last year you could instal the Targa top unfolded in the trunk, the only way the top should be stored. This seemed the perfect segue to discuss the factory hard top targa. Wondering why, and his thoughts on the matter. I am a first time porch owner, and yes, it is a 1975 Hard Top Targa, abandoned 20 year barn find in the process of restoration. Really enjoy his video's. ...
