I had a 7009 before as well and I can't remember the differences. I think I remember something with the amps needed, but I might be mistaken. Again, if someone would just fess up the part number for the E7008, you could change the ugly green illumination to amber in the 7009 as well. No doubt, I said to prevent an aneurysm, but yes, if one is handy and have lots of patience, the LEDs can be changed. Lots of info in the forum about that. If you are a good solderer, then by all means go for it.......
I definitely agree that you'll have a hard time finding the 7008, but that doesn't mean stop looking. The 7006 is a no-frills nav unit. It was the first Toyota nav unit I ever had. No blue tooth, single disc, I don't think it even plays MP3s. Definitely go for the 7007 or 7009. Sorry CookieRoe, not to get into a pissing match, That's cool, I can't remember the differences, but I think you're right... but I could have swore the 7007 was the most like the 7008, not the 7009. I think you are right though that it does some things that the 7008 doesn't. The 7006 was originally for the older sequoias, 7007s, for the siennas, 7008s for our runners of course, and the 7009s were for the solaras. So I guess it would be understandable that each one would do something a little different.
HGIC, if you're interested, I'll probably be selling my E7007 in the near future. Have the additional connectors, gps antenna, I even have the 5th gen 7.1 hybrid disc. Anyway, If you need more info let me know.
