Nav Unit won't go back
 

I removed the Nav unit so I could use the power and optical loop to quickly test a 2nd hand DAB unit. DAB unit worked fine. I reconnected the Nav and now it won't click back into the cage or remove the keys. Nothing is blocking the rear of the unit. Can anybody cast some light on what I'm doing wrong? :Confused:

When I've had my RNS out (which needs 4 keys, presumably the same sort) I remove the keys before putting it back.

Maybe you can remove the whole thing and have a proper look on the bench? It has a 10mm nut and a 10mm bolt. One is on the right had side and is a bolt and the other above the unit in the middle and maybe you can get a tool on by prying the trim back or unclipping it? A 10mm spanner and a 10mm 1/4"-drive socket should be enough tools.

I'm with Andrew on this one - keys need to be removed by pressing on the sprung clip on each side so they release. It doesn't take any force on the key itself to free them. They should almost pop out. Then the unit will slide back into the cage :)

Though I have found units with bent clips that don't release as they should; but it just needs a little tweak with small pliers and/or a screwdriver to rectify - it's obvious when you look.

But that's on an RNS, maybe these aren't as accessible?

Thanks for the reply and suggestions. I left the Nav unit alone last night, will take a look at it a bit later on. +++
