Hi - can anyone help - I live in the UK and I have a MARCH 2005 continental GT reg V12 LCC and am having real problems replacing TPMS. Bentley have told me the infotaintment systems needs upgrading at a cost of £1500 (c$3000); this is because they say they changed the transmitter in 2005 - I have installed http://www.titantpms.com/tpms/bentle...chrome-9455066
and http://www.ebay.co.uk/itm/TPMS-OE-RE...item27d1f834b3

and neither work - I bought them from the USA and understand their maybe some compatability issues - it is costing me $160 a time to try new TPMS's plus the cost of actaully buying them - so this is very frustrating. I have told the infotaintment that I have new tyre pressures - but it tries to learn - and does nothing then - when I switch the car on again it says there is an error in the TPMS - any ideas ?
