Satnav problem on my Avensis

[Greytop]

Just recently my Avensis satnav shows me in the complete wrong place, I have re-calibrated the positioning and direction in the menu. However after a day or two it shows me in a vastly different place on the map to where I am actually in,

Any ideas anyone, ????

Please give som more info about the car and is the sat nav a touch and go or TNS510 for example?

It is a Toyota Avensis registered in December 2008.

The Satnav and radio is built in and does not seem to have a model number,

It's probably a TNS700/B9010. What trim grade is your car?

A picture will be good, sounds like a TNS700 with the flip monitor?

Don't really know what you mean by trim grade. Colour of Avensis is silver and inside trim is black, not leather though.

Thanks, normally it will be a GPS antenna problem or speed signal problem.

In the technician service menu you can see the inputs. But

Cant remember the buttons to press...

I meant TR, T4 TSpirit etc. However, from your photo that you have since posted I can see that it is a TNS700/B9010 head unit.

Hi Scott, Do you know where the antenna for this sat nav is located?
