Temp display with On Board Computer (OBC)?

I have a 1999 Boxster. I was told by my local Porsche dealer that this OBC upgrade will not work on my car because "it wasn't installed". However, I have an outside temp indication below my mph readout so doesn't this mean I have it? Will this upgrade work for me? I don't want to mess around with the electricals unless I am sure. Thanks.

Again, dealers are pretty clueless and often don't know much outside of the scope of what's in the factory manuals. It sounds like a previous owner might have already turned this on in your car to allow you to see the temperature display.

From everything I've read, if you have a temp display, your OBC is already turned on.

Mine was displayed. My Durametric arrived today. Sure enough, it says my OBC is activated.

I've got a few more projects I'd like to do first (the next big one is upgrade to the ROW M030 suspension, Project 63), but I will eventually do Project 91 to be able to access the rest of the options for the OBC.

Anyone know where the outside temp sensor is located? Anyone know the temperature range?

Thanks,

There is an outside temperature sensor located in the front bumper cover. See photo 1 of this article: Pelican Technical Article: Boxster Front Bumper Removal - 986 / 987

I have a 99 also and likewise I had the temp displayed. I did the upgrade and it works perfectly.
