I'm 65 and for most of my driving career (45+ yrs) in which I've been fortunate to have owned many types of sports cars, I really have never viewed any of them as age specific...Same goes for the Supra....
Sadly, I saw this coming awhile ago after a number of people here on the forum, who had unplugged their ASD modules, had to go back and plug it in to perform recall update...Removing / bypassing the OE amp will also prevent the recall update from being installed...
Also after your recall update...
The ASD "overlays" a synthesized low frequency exhaust noise "on top" of the audio signal sent to the OE subs...
There are 2 ways to disable ASD...
1) Using Bimmercode
2) Simply unplug the ASD module...
