Hi all. I posted quite awhile ago about my plan to upgrade my 172 with a garmin 650 and at least one g5. I was going to add a garmin 345 for ads-b in and out. Well the budget just won't allow it and I am also leery of putting that kind of money in my 66. So I put in the sky beacon which is great and I got a gdl39 for ads-b in which displays traffic on my iPad running garmin pilot. So good vfr platform. I still want to get the plane ifr so I can use it to train for my ticket. So new plan: garmin GPS 175, add used king 155 navcom radio with glideslope (I currently have single nav/com no glideslope), add used CDI that is compatible with the king nav com and 175 gps. I'll be into this for about 12k. I know I can do a lot more for close to 20k but it's just not in the cards. Your input is really appreciated.
