I had the radio unit out of my 981 CGTS to find a really annoying rattle/buzz thats was driving me mad for the 3 weeks I had been away on hols in France.

After refitting the unit my CarPlay kit won't work although my phones bluetooth says its connected.

After a bit of faffing I eventually found the CarPlay issue to be a bent pin on the main connector block on the back was bent. I tried to gently straighten to out but inevitably it decided to seek pastures new and made a bid for freedom.

The rest of the head unit works perfectly, just the carplay kit doesn't. My phone says its connected, but obviously its broken on the carplay function.

Who would be able to repair the headunit with replacement pin/s?


PS, don't take the mickey out of me, I'm emabarresed enough already! smile

It should be possible to bend the pins back again, you need to be very gentle, use fine nose pliers and a flat blade screwdriver to easy the pin into shape. I've done it a few times on computer equipment which has been abused.

Im afraid the pin broke off as i tried to straighten it out. It was pretty badly bent.!i was using a small pair of needle nosed pliers and I nearly had it sorted nut as ever, the final tiny tweak broke it.

Not happy, cackhanded muppetry.

Depending how handy you are with tools.........

You'd potentially have to disassemble to board level and desolder the connector. RS / Farnell would have a replacement. Or failing that industrial/electronic repair companies could do it - Radwell / NIE have repaired lots of industrial stuff for me over the years to board/component level.

Easily done.

If the only thing wrong with the unit/plug is one pin could you not open the unit up, solder a cable on it inside at the back of the broken pin, bring the cable out via a grommet on the casing and connect the cable on the external plug with something like a m/f bullet connection to allow for unit removal?

Not an elegant solution but should work.

I’m wondering that as the two pins were touching they might have done some damage to something else.

After my first attempt at straightening I connected everything up and the CarPlay didn’t work so I disconnected everything to check if there was still an issue. It was only when I tried to finesse the pin that it snapped off.

I’m in dialogue with nm automotive who supplied my CarPlay kit to send the whole lot back to repair. They have been brilliant to deal with previously so although it might be a bit expensive (£250+) at least it will be correct.

Always better to do things properly when it is an option, just offered an alternative (bodge) to try.

Let us know how the story ends.
