hello just bought an RX300 and have a couple of questions, as I have a dvd writer could I download an updated version of maps for sat nav and if so anyone know of any websites where maps could be found,,also how do I turn the air suspension off as the handbook shows a switch but mine does not have it fitted just the switch to change ride height just leaving it set to low or is that the default for off mines a 2004 model,is there an easy way to look at cam belt as mine has been changed by the garage I bought off but like to see for myself have a good local garage who could check but got a years warrantie and cambelt failure is covered but even though getting a recipt for work done as an unknown garage has done the change am dubious .On the plus side the car drives superb had Jags before and not a patch on the Lex or Tank as wife has named it . thanks Bob M
