I'd like to get a new panel installed on my M20K here in Switzerland. Right now it has two 430W's, a EDM700, GMX200, and Sandel EHSI. I'd like to install a G5, an EDM930 (instead of the 700) and a GTN750. Has anybody done this? Or has better ideas to clean up the panel? Pictures of the panel are below.

I have fretted over updating my panel for years and now that it is sitting in the avionics shop I am being hit with a lot of valid and challenging self-induced questions. So I decided I would turn to my Mooney family for some opinions, pros and cons around what I am about to share. Besides, I am sure all of you are sitting around today wishing you had not had that second plate of food or sneaking back into the kitchen after your nap. But the real reason I decided to post is due to so many pictures of Aspen installs in Mooney's but no one removed any of their round gauges...hence, the questions as to whether I am making the right decision. Before I taxied up to the Avionics shop: My 1981 J model had the "out of the factory" round gauges with the only upgrades being; GNS530W, panel mounted 696 (AirGizmo) and EDM700 Original plan before taxiing up to the Avionics shop: Install GTX345, GMA345 and a DAC GDL31 GPSS...and I was also pondering installing the stratus USB charging ports As time progressed and Aspen came out with their reduced price to include synthetic vision, EA100 blah blah blah...the questions and options began to fly: So I decided to add another zero or two to my panel project and the Aspen is now on its way as well as the post purchase remorse. Well since the panel is torn out, why not include a Flight Stream 210...what the heck, let's do that too. What are your plans for backup AI, I honestly had not given that much thought because silly me, I "assumed" the Aspen would shed the need but WRONG, only with the MAX upgrade. Ugh!! What about installing an Aspen MFD, nope my budget is shot! What about relocating the KI256? I realize that is a possibility but I really wanted to shed my vacuum system (I expect a lot of "opinions" from you guys on this topic) What about installing a G5 as your AI backup? Hmmm, I really like that idea So if you're installing the Aspen PFD with a Garmin G5 you know you can eliminate all the round gauges. YIKES !!!!! Did you just say remove all the round gauges???? We would suggest installing the Aspen, G5, retaining your #2 VOR, EDM and install a new pilot side panel...no plugs no holes, fresh, clean and only $1k more. And we will back mount everything. Just for the record, my overall plan is to build for future panel expansion and including the MFD in about two years. Summary and my ask for you guys: At the time of this post I have decided to follow the shops suggestions of installing the Aspen, G5, relocating my EDM, VOR #2, reposition my AP annunciator panel and basically reducing my instruments to about 50% of the panel with the other half clean. And so I can say I said it, I completely get the transition training involved with moving away from round gauges so let's allow that to be a given for the moment. Now it's your turn to fire away and I would like to say " thank you", in advance Rick PS, the attached panel was just me inserting equipment to get a picture of the final product before the idea of removing all round gauges entered the equation.

Dear All, I recently upgraded to GTN 750 and I noticed that there is no switch to turn it on and off. Everything appears to be under the radio master, moreover when I switch off the radio master the shut down of the GTN comes abruptly and not gradually as it was with my old GPS. Is it normal?

The King EHSI died, over $14,000 to fix, Ouch! So, we picked the $50,000 fix instead!

I've acquired a number of good used Klixon circuit breakers of the 7274 (MS26574) style. I have many different amperages. PM me to see if I have the ones you need. $7.50 each plus shipping.

I knew when I bought my "new" 1968 M20F model a couple months ago there would be a few upgrades I'd like to do. She's actually got a very nice panel, good interior, and serviceable paint, but after a few recent IFR flights around Texas, I think I'm about ready to put in an Aspen PRO PFD 1000. I think I'll be $$ limited to just the one screen for now. I was hoping someone out there would have some experience with this and give me some round number estimates or even a recommendation for avionics shops with Mooney/Aspen experience (I'm based in SW Texas). Here's what I've got to hook up to it... STEC 30 with Alt hold, Garmin 430, and a Garmin SL30 #2 NAV/COM. I'd like to remove the whole vacuum system when I do this, so I understand I'll have to purchase an electric B/U ADI. What am I missing? Anyone have any clues how much it will cost, where I should go to do it, or what else I need to do to get rid of the vacuum system? Thanks so much for your help, I'll attach a current panel picture just in case you want to see what the previous owner did for me (thank you!)! Rags
