Agreed!

My understanding is that the Nav uses the Vehicle Speed Sensor (VSS) to match up with the GPS satellite.. The two then work in concert to track location and speed.

The problem is that the NAV unit doesn't receive the VSS signal properly.. or doesn't decode it properly.. So the GPS beacon is giving an approximate change in location, but then the VSS signal is saying somethign completely different.. so the system freaks out and says GPS signal lost until it can figure out how to sync up.

Mine drops signal by the end of my street every single time.. it can take anywhere from 2 to 20 minutes to pick up signal again.. it's basically worthless right now.

The issue isn't the initial acquisition of satellites, it's maintaining them. If I'm parked, I'll typically get an accurate location within 30-60 seconds, however once I acquire a signal and set my route, once I start driving it either says GPS signal lost, or it thinks I am 5-10 miles away on some random road.

The temporary fix is here and it works: but one post said it is only for those who's Nav almost never gets a position lock. Since the fix my Nav gets lock quickly: so far taking no more than 3 minutes to lock on wooded roads. Sometimes when it hasn't been driven recently it now only partially locks for the first minute- with the position jumping around- but then fully locks within 3 minutes. Once fully locked the position stays correct for the rest of the trip. Here is my post about getting the fix:

The permanent fix (TSB) for anyone with GPS reception issues is scheduled to be ready sometime this month.

I actually like the Nav system when it works. Better than my Jeep, not as good as a standalone unit though.

Has anyone else had any software issues with the navigation? i.e. unresponsive buttons, if you slide out the audio control mini-panel it'll just freeze and get stuck there and if you press other buttons those panels will slide behind it, etc?

For the one trip I used the Nav I did not have those problems.

After that one trip I bought a new standalone garmin and haven't activated the map since on the shitty Subaru unit.

To be fair, I've never used the nav for turn by turn. It seems like more of a PITA than just telling SIRI I want to go to XYZ and turn by turn starts working (beta of IOS6). I stream the turn-by-turn from the phone via bluetooth and just use the Subaru's on-screen map as a reference while listening to the phone.

Works excellent this way!

Great news as I have the same issue. Seems to happen at least 50% of the time right as I hit my favorite curve leaving my neighborhood. "GPS Signal Lost".

TSY · 09-13-2012, 10:01 PM

Well I've been driving around for a week with the Nav update and it seems to be working pretty well. It finds satellites right away and puts me in the correct location when I start the car even if it has been sitting for a few days. I only found it confused once but it corrected itself quickly.

I had it guide me home through tunnels and it worked fine, so so far so good!

Any magic words or repair references to share, guys? My dealer still keeps telling me that the update isn't live yet. "GPS signal lost" is getting really annoying...

Yeah this is what I was going to do... until I found out they won't be supporting turn by turn for iPhone 4, so I would have to update to the iPhone 5. Fuck Apple. I'd rather not spend $200 to get a phone that looks like a 1980's TV remote control.

Not sure. I bought my BRZ from one of the largest Subaru dealers in the country and Subaru sent someone to come and fix my nav. I'm sure it will be available soon. Just keep bugging your dealer.
