Today is my first day of MX-5 ownership I've bought a really clean, 2006 2.0 Sport and it's a definite grin generator!
The only problem is the Bose stereo is displaying the flashing "Err" message. Of course, i've googled the issue and have come across the steps required to enter an 'override' code:
Step 1: Press the following sequence; Preset 6, AM, Auto M, Seek ^ (up)
Step 2: Four dashes appear, at this stage enter one of the following codes; 4989, 1414, 1515, 3511, 5989, 3211, 2312, 0532, 5011, 0000
