Recomend me an inline 12v on off switch please?

[Comfy Old Boots]

I recently bought a cheap chinese car play unit for my bike. I guess you get what you pay for but over all I'm very happy with it.

However! I've it connected to the 12 v accessory socket at the front of the tank. the one the gps is normally attached to. Now the issue I have is that when the car play unit is on, it will not let the bikes switched power turn off! I have to do a dance with turning off bluetooth and wifi and make sure it's not still recording. It's becoming a bit of a nuisance. I've read somewhere it can be down to the unit drawing too much power to allow it to power off?!

What I'd like to do is just wire a switch onto the power cord down under the head stock. Something I can just manualy turn on and off when I get on/off the bike. I'm having a bit of trouble finding something suitable. Am I looking for a 2 pole switch? Just want a basic inline jobbie. Any suggestions? Thanks!

If you want a switched live -

the only one i could reliably find that was easy to get to was to take the switched live feed from the round diagnostic plug under the pillion cover

i just spliced in a extension loop and spliced in a wago 2 - 3 way connector

Given that you're talking about a bike where the switch might be exposed to a lot of spray/water, I'd search chandlers for a simple water resistant in-line switch then plumb it in using heat-shrink over the terminals.

Hoping for something fully enclosed but I could make that work.

I’ve got the spots switched off the rear aux socket. Cable too short on the car play unit to run that far and I’d have to get another relay etc

Think this looks about right. can just stick it somewhere handy down there

Relay welded shut?

Relay welded shut?

a mechanical relay? How quaint.

hasn't BMW used a solid state ZFE since the first 1200 came out?

No the lights are on a relay switched off the rear accessory socket. The car play is powered off the which power socket under the front of the tank.

I’m riding a 2007 so pretty old I guess.

first 1200 was in 2004 when we had the delights of ZFE and canbus imposed on us

Still not sure what your point is? The CarPlay is attached to the campus/zfe at the front? Anyway I think a simple on off switch will sort the issues. If the car play is on the bike will not switch off and I’ll only need it when out for a fun spin.
