Dear Mr Webster
Thank you for your recent enquiry with regards the problems you have experienced with your satellite navigation system on you Lexus IS 200.
Unfortunately, we are unable to offer a technical diagnosis to the particular problems highlighted in your correspondence. We would therefore ask that you consult with your nearest Lexus Centre as they are best placed to offer the technical advise and expertise your require in order to investigate and answer the questions you raise.
I can confirm that having spoken to our Technical Department at Lexus (GB) Ltd we are unaware of any major issues with the satellite navigation system on our cars. Historically, I would clarify that Lexus do not supply individual components for the satellite navigation and that it is usually provided as one single unit.
In closing, I would like to thank you once again for bringing your concerns to our attention. I would strongly recommend that you car is looked at by a Lexus Centre who may then be in a position to liaise with Lexus (GB) on your behalf.
If you have any enquiries or require any further information please contact me on 01737 367601 (telephone) or 01737 367721 (facsimile) or at customer.relations@lgb.lexus.co.uk.
Yours sincerely

I contacted my local dealer and they were unable to help. So now I’m going to ask, what they do with all the old units that are broken, as they only seem to swap out the whole unit.
Watch this space.
