Having reconnected the battery after doing some unrelated work I had to reset the satnav to UK and English language. When you set to English you are offered Km or Miles and I selected Miles. The setting for the satnav was changed correctly and guidance was displayed in miles, however for the trip computer all distances are shown in Kilometres - Range, Distance, litres per 100 Km etc - and no matter what I do it will not change back to miles. I tried disconnecting and reconnecting the battery again and also removing the CD from the unit under the passenger seat and reinserting it but to no avail. I am afraid metric means nothing to me and I want miles and gallons back. I have the TNS300 manual and have followed the instructions to the letter. Does anyone have any ideas as to how I can reset my device.
