Having just joined the forum I see that a speedos are a bit of a problem on GTAs.
Mine has suffered similar symptoms to others posted, ie. working intermittently and now not at all. Unfortuantely I need at least the trip computer to be working for my limited mileage classic car insurance.
Apparently its a common problem with the "speedo head unit" but the only solution appears to be a replacement which is about £700+
as the whole binnacle is needed.
Are there any other more palatable options such as repair and/or 2nd hand units - I'm even contemplating getting a 3rd aprty speedo such as a "Stack" unit and setting that up to work.
Any advice would be much appreciated...
