RetroSound HB-111-51-74 Hermosa Direct-Fit Radio for Classic Vehicles (Black Face and Buttons and Chrome Bezel)

Do not buy this for the usb access most do not work with the car running. USB stick works fine when key is in accessory mode but once you start the car the usb media skips constantly.The bluetooth solves that issue but its a feature you pay for and for it not to work is dumb.You've been warned.Im going to see if I can live without itRadio cuts out when the vehicle is runningThere are five main issues that cause this problem:Poor ground or shared ground with other electronics. Move the ground to a clean location or ground the radio directly to the negative battery terminal. Check the ground from engine to firewall. Install a ground strap from the engine to the vehicle chassis.Ignition voltage is erratic. Test to make certain both power sources are good. Use a digital multi-meter, not a test light. Make sure both the RED ignition and the YELLOW constant do not have spikes or drops in voltage when the engine is running. The radio needs constant voltage of between 11 and 14.9 volts.USB cable routed near or over ignition or high current wiring. Make sure the USB cable(s) are not wrapped up with the ignition harness and are routed away from the vehicle’s ignition switch. Do not coil extra USB cabling.Old vehicle wiring. Remember that, in most cases, we are dealing with vehicles that are over forty years old, with forty year-old electrical systems. Older ignitions -- such as Lucas wiring -- and many other older vehicles simply need to have updated plugs, wires and caps installed. Solid core spark plug wires offer almost no resistance to RF interference; braided plug wires are best.RF (radio frequency) interference caused by HEI or MSD after-market ignition systems.MSD: make sure main control box is isolated from the firewall (MSD ignitions come with rubber boots for the module. Make sure to use them!). Also make sure it is not sharing the same ground point as the radio. An MSD 8830 ignition coil filter is often effective at isolating the RF interference.HEI: if your ignition is too advanced it will cause premature spark, creating RF interference. Adjust the ignition so that it does not fire prematurely. Some vehicles with HEI ignition need RF shielding on the ignition part. Another alternative is to put shielding -- such as ferrite coils -- on the radio’s USB cables.Inspect HEI: check for cracked or loose distributor cap. Check for carbon build up. Check rotor for burned black spot on wiper, or for pits in the surface. Test the coil to make sure it is functioning properly.Because our radios feature an external USB cable on a three-foot umbilical, the USB cable itself can act as an antenna for RF interference. Some vehicles simply either have too much RF interference or other wiring issues to be able to use a unit with external USB inputs.

Generally happy with this purchase. Well thought out design for relatively easy installation. The one thing I dislike, is the delay at Start-Up. When you power up the unit (by knob or when it automatically starts if it was On when you last shut the ignition off), there is a significant delay before the unit actually operates/functions. Seems like 30 seconds to boot up every time you shut it off then re-start it. Annoying!!! Other than that, I like it.

Installed this on my 1977 chevy looks reall good & love that it has blue tooth .

Installed in a 1966 Pontiac GTO. Fits perfectly without any mods. Sounds great. Love the Bluetooth.

Love the classic look of this radio but the convenience of a modern one. Easy to install.

The unit ordered was the Hermosa which included bluetooth connectivity. The item received was the laguna which is a cheaper model that does not include bluetooth.

Nice add to the Retro-Restore of my 1969 Camaro...

WOULDN’T BUY AGAIN. Was a pain to install and get it straight and tight. Takes a 5-10 seconds after turning the car on for the radio to come on. Quality feels likes it’s worth $20. First time I run the car after install it sounded pretty good but by then later that day the sound cut out so I u plugged the harness and plugged it back in and the sound came back but sounds worse and less clear then factory am radio from the 70s.
