Guys, just got an airplane with the 650xi and I am looking to get traffic on it and weather. I am learning that I need the Flight Stream memory card to get traffic? Does the Flight Stream 510 memory card replace the existing card? Also, does the Flight Stream memory card give you ADSB traffic & weather or do I need to get the GDL88? Or should I just get the GDL88 to get weather and traffic and forget the Flight Stream 510? Thanx.
I'm going to repeat a couple of things others have said, but I think it is important to think the whole process through.
First, what Transponder do you have? And have you checked on the 650's Traffic screen to see if you're already getting Traffic? Traffic and Wx need to come from an ADS-B **IN** device and often that is the Transponder. Though as you said, you can buy an external device like the GDL88 if your Transponder is not ADS-B In/Out.
Next question is what else is in the panel, do you have a GI-275, GNC355 or GPS175? They have Bluetooth built in, so you may not need to buy a FS510. You can connect your EFB to one of those devices that should allow you to get Traffic, Wx and send Flight Plans to/from the GTN. NOTE: All the devices need to be configured correctly for this to work. So if you one of these other devices and it does not work at first, check with your avionics shop.
And as others have said, no the FS510 will not give you Traffic or Wx. It is just a WiFi and Bluetooth device to make up for the shortcomings of Garmin for not installing it in the first place. (I get the orig. 650 didn't have BT, there is NO excuse why the Xi does not.)
Also note if you do have other devices. With your Garmin OnePak you can create a single update SD Card for your Garmin devices. You then update the GTN with that SD Card and then the other devices will be updated from the GTN. Again, this needs to be configured correctly, but it is the normal setup and should have been done at the installation.
