Money Back Promise

We're real guys not a robot, so if we are not able to supply the factory-set code, we will clearly explain why and offer options on how to proceed. And we promise to refund you less 95p which we have to retain to cover the payment processing fee.


We aim to reply within 1 hour Monday-Friday, a little longer evenings & weekends. Most codes are £7.95 (£14.95 for Audi, Skoda, VW, Nissan & Jaguar) for a personal service. We're proud to have helped customers even when the car dealership was stumped, and at a much lower cost.


Sometimes our responses are lost in the customer's spam mail. We routinely send copies from two different email servers, but if you've not heard from us within 4 hours, please send an alternative email address to admin[at]

InCar Technology Help & Advice

Here's a video tutorial on setting up the type of equaliser built into many car stereo units. I use a spectrum analyser to show how the frequency curve changes.
I have also retained some content from the old MMSA website as some may still find it useful:
