Change Tns310 To Tns700

[kesindi]

I am new to TOC and this Forum. Please allow for mistakes?

I have an Avensis Estate "T4" 06 reg. This comes with sat/nav model TNS310 and I was wondering if it is possible to update this to the new TNS700 full coloured sat/nav. I have been to my local Toyota Dealer and they were no help at all, first saying it isn't possible and then saying it would cost £1,000's to purchase and install. I thought about ringing technical helpline but reading this forum they do not seem to be very helpful.

Has anybody tried to do this, or can anyone offer advice?

Thanks from as newbie.

I wouldn't mind doing this as well if it's possible.

Hi Yes TNS700 can be retro fitted to your car, instead of TNS310.

It would cost alot as the TNS700 unit will be hundreds from Toyota, you will need a new fascia as the TNS700 also controls all audio and you lose the headunit you currently have, you will need new wiring plus a new DVD map.

Honestly it will be very expensive unless you can get the unit cheap

Thanks for the information Smoftah,

It seems like it will be expensive with the new facia and all. Will have to wait till I next change my Toyota.

Thanks again.
