[Celica navigation system]

Re the OEM Sat Nav they can be updated to the TNS300 DVD with the Tmc option and the last CD availableis around 2011 as far as I've been able to find. Works fine enough for me and saves me piddling about with a touch screen while driving.

Does the TNS dvd unit just plug in ? See there are a few on eBay, does it give you the facility to punch postcode in ?? And does it work with std nav head unit ?

The Toyota satnavs I've had all work on the first four or five letters of the postcode, which is hardly precise. And they have been very clunky to programme by street address.

Not sure if you can enter the postcode in mine ?? Seems only city's and street names

It would be in the boot as got a 6 disc in boot too as well as the sat nav system. Might have a look round my local breakers yard.

What people's views on the std t/sport navigation system ? I have been experimenting with mine and it not up to today's quality but it's ok .

Can they be updated with a current cd and also to include postcode entering ? And would something like this be a plug and play option http://www.ebay.co.uk/ulk/itm/252208778507??
