Jumbo Jet

I just noticed the other day that when I hit the nav. button on my 8120 it just goes to a black screen. The rest of the 8120 seems to be working perfectly.... except for the blacked out nav. screen. I know that the Garmin nav. on the 8120 is hard drive based so I'm wondering if the HD has crashed or died..... I tried resetting the unit but still no luck. Anyone else run across or heard of this issue before? I'm calling Kenwood on Monday but just looking for ideas first.

Will do, gonna tear it out this weekend and ship it out on Monday. I talked to the repair center and he said they have a 1 week turn around on average...... we'll see. Other than this its been an awesome HU, more features than I can even use, this is the first problem I've had..... albeit a big problem, but all Excelon units have a 2 year warranty so I should be good to go.

A quick call to Kenwood doesnt get me too far. They are recommending I take it out and send it to their repair center for a check up and fix. Guess I'll be without a radio in the truck for a week or two. It appears they are aware of the problem, I'm calling Garmin in the morning too to see what they think. But sounds like Kenwood will just reinstall the software.

how long have you had it? I'm looking into getting that system, but not if features are gonna crap out. I've had it about a year and a half. Other than this its been an amazing HU...... but this is a big deal to me cause its the reason I spent the extra money in the first place, the nav. Now its not working. I'll call Kenwood today and see if there is an answer. According to a few google searches..... I'm not alone with this issue, but I cant find any solutions online.

I made brackets like that for my Tundra last year. I used an upright belt sander and a jig I made. I made my speaker rings first (base plate was 3/4" MDF and mounting rings are 1/2"), then made a jig that was just a few mm larger than the ring out of 2 pieces of 1/2" MDF. I cut out the slightly larger diameter on the top piece only, the bottom was solid. Mark the center point of the jig and then mark the center point of the speaker ring (mark both sides of the ring). Then I took a small piece of MDF and glued it to the outside edge of the jig inside the circle. I glued the speaker ring to the jig by using just small dabs of glue on the peg. Once its glued the speaker ring will rest slightly higher on one side, that is the side that will be sanded off. I ran it across the sander using 50 grit paper until the ring was flush with the jig. Once the rings are sanded I mounted them to the base plated with glue and screws, then a fresh coat of flat black and finally a sealer to keep the moisture off. Hope that helps
