2009 TCH Navigation System - Toyota Nation Forum : Toyota Car and Truck Forums

The car was sold without a Navigation system, but is satellite radio ready (SAT button on head unit). The car has what appears to be a factory installed antenna located on the center top of the dashboard (above the clock). In researching this antenna, I noticed the FSM indicates the antenna is a GPS antenna. Does anyone have experience or knowledge that can confirm the presence of the GPS antenna indicates the TCH would also be navigation system ready?

Thank you.

I think I've figured it out.

What'd you figure out? Could you post a picture of the so-called antenna? I don't think I've ever seen that before.

prolly Sirius radio antenna.

What I thought was the gps antenna (mounted in front of the clock) is the photo sensor for the auto headlights, I believe. The gps antenna is mounted under the dash and cannot be seen unless you take out the Nav system.

I just received the factory Nav system today (E7011: P/N: 86120-06460 and it looks like it's in excellent condition). I ordered the wiring harnesses from a Canadian Toyota dealer and should get them next week. I got the gps antenna and Nav disk on ebay. I still need the AUX jack, and if I cannot find one at a local pick-your-part, I'll need to purchase from the stealer ($100 ouch).

I'm planning to install next weekend. I'll take pictures.

If it goes off without a hitch, I'll add an XM receiver and Lockpicks (so I can program GPS while moving).

What you mistook for an antenna is indeed the light sensor for the dashboard lights.
