Satnav Problem, (New To Lexus)

[dtmwelburn]

Hi all, i bought my lexus IS200 SE a couple of days ago, (what a lovely motor), only issue i have with it is with the satnav unit, when i switch the ignition on it flips open and displays "LEXUS" and then switches off? can anyone point me in the right direction of repairing this? im pretty handy with motors and minor electrics so not afraid of having a go myself, just looking for pointers :)

Im told the previous owner had a aftermarket system in so is there any telltale wiring changes i should be looking for?

All help is massively appreciated

Thanks

Dan

Hi have you checked to see if it has got a disc in the module in the boot?

Hi there, yes i checked that first, and the disk is present, although there are two plugs on the unit that have nothing plugged into them? not sure if this is normal,

Hi,except i have a look at mine(at work at mo)I cant tell you,but my feeling would be that they should plug in somewhere.
