This is not a probability of success.

But now the problem is when the key is turned on in the first position ( not turning the starter) the radio / CD works fine but once I start the motor the radio turns on and off constantly.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I got my Becker CDR 210 working (found the code) on a recently purchased 1999 boxster. But now the problem is when the key is turned on in the first position ( not turning the starter) the radio / CD works fine but once I start the motor the radio turns on and off constantly. I’m not sure if it’s the radio or the power supply.

POST 2Original post

Any other strange behavior from other accessories ? Many here like me will suggest a faulty ignition switch.

x2 (but message too short)

POST 4 / ORIGINAL POSTEROriginal post

Everything else seems to work fine. It’s the base model so not a lot of accessories. Windows, top,HVAC, Cruise control , wipers, and lights all works as they should. I would expect other issues if it is a ignition switch. How do you check for something like this?

X3 Search on here for ignition switch problems. Extremely common for the switch to go bad. I think a new one is $25-35

POST 6Original post

X4 Turn the key slightly to the left and see if the radio stays on.

Why? Why would you expect other issues? Everything I've read about ignition switch anomalies suggests it could be just one issue, or many. I can imagine how annoying it is, and I'm waiting for the day for one of those anomalies to surface. The ignition switch will be my first go to. Good luck.

POST 8 / ORIGINAL POSTEROriginal post

I just drove the car today and the radio faded it in and out for the first 10 minutes of driving and then it started working fine not sure what the problem was

Sounds like a wonky HU.

This is a source reference. Confirm exact model applicability in the original material.
