New to me 2008 Prius, first hybrid. Few ?'s.

If you Google "2008 Prius brochure", you'll find doc that can help with comparing option packages (not letting me post link). Think you have #3. It says there are 9 speakers in 7 locations.

I'm pretty sure that's what the MP3 means, as you said.

 

If you stand in front of the car and look at the dashboard through the windshield you will see the 9th speaker located above the multifunction display.

If you had the navigation unit, it would be located under the driver's seat. The JBL audio amplifier is located under the front passenger seat.

 

Too bad you don't have that salesman statement in writing about Navigation disc. Did you even believe him?

Package 3 if you have the back-up camera and a rear view mirror that auto dims with the "Homelink" feature. Do you see the garage door button at the bottom of the rear view mirror? If yes, then Package 3 most likely. It may be possible that yours could be a non-conforming Package due to massive corporate leasing companies cherry picking specific options to add onto a stripped down base model.

Inside the center console, there should be a 3.5mm mini headphone jack (aka Auxilary audio jack). You'll need a male 3.5mm stereo cable; one end goes to center console, other end goes to the phone/iPod/MP3 player. This will be the cheapest/easiest way to stream music.

If you have money, and want modern conveniences, upgrade the head unit (AKA stereo) w/ a double DIN Navigation head unit. You'll have built in GPS and Bluetooth stream capability.

You should be reading Gen2 Prius Audio and Electronics. It will give you ideas on modifications to add a lot of electronic creature comforts. Also, Gen2 Prius Accessories & Modifications is another good sub-forum to check out.

Get the transaxle (think transmission) fluid changed ASAP, unless the previous owner(s) changed it. You can look up the service records for this car on Toyota's website, if they took it to the dealer for service and the necessary recall work. LINK A simple drain & fill, just like you would on a truck's rear differential. NO flushing like true automatic transmissions.

Tinted windows will be a nice touch to add.

 

Yours is Package 3, unless you notice items that don't belong.

For example, my car was a company car, from a large corporate leasing company. These companies order thousands of cars and can custom pick specific option(s), not being bound to the consumer retail Package 1-6. Mine doesn't fit Package 1 or 2, and definitely not Packages 3-6.
