I have found a German website where I can just buy the GPS antenna, it'd be great if it worked. I have a question for you, did you buy a whole new head unit? Do you think it would work if I just bought the GPS antenna to add to my 'touch' unit? I guess I would then have to buy the maps and possibly update the firmware also. Payment can be made by credit card The Navigation Map Update will be delivered within 3 to 32 days of the day after the consumer placed his order before finalising the order of the Navigation Map Update, an advised Expected Time of Arrival is suggested on the Map-Updates Website, but TME does not warrant that delivery will be made at that date. i shall look into it and see whats worthy what. My other half definitely thinks it was worth it!Īww thanks for the info. Yes, it is still expensive, but on balance I think it is probably worth it. Once fitted the Yaris has full Touch and Go functionality, including proper album art displays, sat nav and added MP3 music selection functonailty from USB.

The add-on 'Go' box worked straight off, and just needed ten minutes or so to get an initial fix and reset itself from the factory location in Germany (these units are made by Harman in Germany, so default to a German location until they get their first fix post-installation). It was all of ten minutes work to fit and needed very little in the way of skill (just a plastic tool to help prise the dash panel off plus an 8mm socket and long extension to undo a few screws and re-fasten them). I bought a brand new 'Go' unit, with current maps and all the cables, GPS antenna etc for £430. Yes, it is expensive, but if you shop around you can get it for less than Toyota charge. As a sat nav it is reasonably OK too, and being integrated into the car does make it easier to use and less unsightly than an add-on sat nav or spart phone on a bracket. It enables album art displays when playing music from USB, and allows more comprehensive searching (by title, artist, album etc). The add-on 'Go' box is more than just the sat nav, though.

A quick spec check showed that this was an optional extra, as you've found. Needless to say she was a bit upset when she got the car home and found that the nav button just gave a 'system not installed' message. She bought an ex-demo Yaris Hybrid, that had a lot of extras (panoramic roof etc, etc) and as I already had a Plug In Prius, I took one look at the Touch system, saw it had a 'Nav' button and assumed it had sat nav.
