This is my second Huracan (610-4 now Perf Spyder). BOTH have had the same issue in that they will randomly lose all presets. I can not seem to understand why or when it happens. May be tied to using different keys, but that shouldn't cause me to lose all presets. I was told this is not a common issue but to happen to BOTH cars I doubt it and wonder if anyone else has experienced this frustrating event which seems to happen about once a month!

One possible thought is that you are killing battery power to the car thus resetting the radio. Is it changing the clock as well? Maybe you have a battery kill switch getting engaged.

It hasn't sat more than a couple days when it occurs...What/where is the battery kill switch? I do have keys stored in a drawer that may be getting crowded and something may be pushing key buttons for extended time? Another thought was that I do have a Tile (Bluetooth tracker) on my keychain. Wonder if this is setting it off somehow.

My perf spider does not do that. I would be interested in hearing what you find.

In all my huracans including my Performante this has never happened. I wonder what can be causing it

Agreed with the battery/power interrupt scenario. Make sure terminals are Tight, should not move, twist back or forth. Any malfunctioning installed accessories that could trip a circuit breaker or interrupt power.... Similar experience but would also randomly lose sound. Found corroded terminal exposed to outside elements acted like a resistor. Took awhile to trace it down, but no issues since cleaned and re-connected now with dialectric grease !!

Unfortunately I only have a Murcie and Gallardo so dont know where the kill switch is. On mine it is in the engine compartment near the battery (which is in the fender well) on the Murcie. The G and Jalpa have the battery in the front. I would find the kill switch and make sure all connections are good and it is not malfunctioning. Also check battery connections and test the battery. Are you using a battery tender? The connector could be grounding out and killing presets. I would find an old analog clock that runs on 12 v dc and see if it loses time between running the car. If you have intermittent power failure, the clock will show it. Make sure and connect to a continuous power source but not directly to the battery. Just make sure the clock stops or resets when the power is killed. Some clocks and radios have a rechargeable internal battery that keeps time when the power is off. I would also check the presets to see if they are being killed as the car is cooling off. There could be a short that is touching when the engine cools off thus killing the radio. Go check the car at 15 mins and 1 hr after shutdown then see if the presets are still good. If not, you probably have a short that occurs during cooldown or the battery voltage drops during cooldown until it kills the presets.Run some tests and let us know. Information is key when chasing electrical problems. Eliminate the obvious first then dig deeper. (Battery, connections, etc)Many batteries now only last a couple of years. A lot of things have threshold voltages to protect them. Once voltage drops below a certain point, it shuts down. It may be dropping when hot after shutdown then recovering enough to start the car. Another possibility is a sticking relay keeping power on to systems that are drawing power until it cuts off the radio. It could be intermittent. Also are you in a salty environment?

Hey , also if you are in DFW , I have a code reader , voltmeter and battery tester. I am in Aledo west of Ft Worth.

One local guy mentioned he also experienced the radio preset twice. He recently acquired his lamborgini and the previous owner had an accessory installed. I'll ask what particular accessory was installed when he returned this week for the installation of the new set of tires and dually wheels on his truck.

Never happened on my 2 Huracans. I usually stream spotify with occasional FM radio. Let us know what you find out.

I wonder if the other guy having this problem occur bought my old one. This does bring up something I bet may be the cause. I had my Escort 360 Max installed and hardwired to the fusebox in passenger seat bay. Same place installed both cars. I bet this may be the culprit. Thanks all for ideas.

If it was car toys you can bet on them screwing it up. Many installers have no idea what they are doing and tap into systems or circuits they should not touch.. My daughter had a new stereo installed in the Hummer we gave her and had constant electrical problems since then. (Returned it three times and finally gave up) I am going to have to remove the radio and all the connections they made . I just bought her a new car and am going to keep the Hummer and work on later when I have time. I would not let anyone but myself or the dealer touch the wiring on my Lambos. Most installers have very little real knowledge of auto electrical systems. They are taught a few basics then cut loose to wreak havoc. Modern electrical systems are very interconnected and dependent on voltages in many cases. Most of them just take a probe and look for a constant hot and a switched hot. However some lambos use switched grounds and power up relays that connect to larger circuits. My Jalpa had many rigged connections made by alarm and stereo guys. After removing all of them and repairing correctly all the splices and rigging, it now works great. I would remove all the connections they made and correctly repair any damage they did. I bet your problem will dissappear. You can plug into the cig lighter in the meantime or power port.Good luck. lee

It was not CarToys. It was BestBuy...lol. They did both my R8s and I was very impressed with the guys credentials when asked up front.

The guy at car toys had 15 years and was very experienced also. It does not mean he is qualified to work on a Lambo. Best Buy and Car toys all hire installers at about the same pay scale. If you want experts, you have to go to a high end specialty car stereo place. They will actually look at the cars wiring diagram. If they domt need to see that then they probably dont know enough unless they have already done a bunch of lambos. I know a lot about auto electric and even build my own wiring harnesses. First thing I would do is look at the diagram and find the Correct power source then tap into it without compromising other systems. Lambo electrical systems are some of the weirdest I have ever seen. Some things they do completely defy logic and reason. I have not worked on any of the real late model stuff but expect some of it is there as well. Lambo wants everything to be done by the dealer. Make it difficult and confusing and you will end up there one way or another. Lee
