2004sc

My SC is a 2004. I believe it has the Gen 2 navigation system in it if what I have read on this site is correct.

If I "upgrade" to Gen 4...
1. Does the hated "I agree" go away
2. Is this a simple "plug and play" upgrade? Take out the old player and put in the new one?
3. Any other benefits to updating other than being able to get a newer map?

Thanks for your info and help.

Most people upgrade to Gen4 because the Gen2/3 player fails. That's what happened with my 2004 SC430. So my decision to upgrade was easy.
Here are some answers :
1. Yes, the "I Agree" screen will be present. The hacks to get it bypassed only worked with the earlier map versions and at some revision point, the hack no longer worked. If you plan on getting the latest version map, expect the "I Agree" screen to be present.
2. Yes, simple plug and play upgrade. You will however have to take the trunk slightly apart to get to the DVD player. Not hard, but time consuming. I was actually sitting in the deep well area to do the swap.
3. Aside from more current maps, the visual display and user interface is improved. I never had the opportunity to play around with Gen2/3 as it was pretty much in-op when I bought the car but other posts from owners with more Gen2/3 experience mentioned the improvement.

How do you know what Gen you have? I have 2007SC

FlopTop04...thank you very much. Just the information that I was looking for. My NAV still works just fine and the truth is I seldom use it anyway. Would love to get rid of the "I Agree" message since it is an aggravation and is so out of date to have to punch it every time. But, if Gen4 doesn't get rid of that, I'll just save this money and spend it on something else. Again, thanks for your reply.

GmanSC...I do not know how to tell what Gen you have, but I'm confident that someone on this forum would know...or your local dealer could tell you. I have an '04 SC with the original Nav system in it so I was pretty sure I did not have the latest version. Seems to me that I have read somewhere on this forum that members were replacing their Nav's with Gen 4 systems from '06 Toyotas they bought off of ebay. If the '06 Toyotas had Gen 4 then it would seem likely that your '07 SC already has that.

FYI, you are Gen 4.

2007 SC would have a hard drive GPS...or was it the 2009/2010 who had it?

Nice find sblevins!

Mandyfig, according to the chart that sblevins linked to, that would start with the 2010.

My nav works fine in my 04 Sc430. But recently all my marked points are being displayed on the screen. Anyone know the steps of getting back to a clear map screen?

Have you accidentally hit the POI button?

Sammie10

Good thought, but I thought of that too. The POI screen allows removal of them from the screen but not the marked points. It's still a head scratcher.

Thanks. You know what, I read this chard few months ago. How could I forget? Old age. .

Try to clear the history.

One of the side benefits of the VAIS iPod unit is that it disables the "I Agree." For me, that's worth the price right there!
